Fighter Aircraft

Fighter Aircraft are currently broken into 5 Generations. However, the verge of a 6th Generation is nearing.Additionally to bridge the gap of technology between Legacy 4th Generation & 5th Generation many countries have outfitted Gen-4 Aircraft with 5th Gen Tech. This is called 4+ and 4++ Gen Fighters.Basic Fighter Maneuvers (BFM)-The Ops Center By Mike Solyom, VideoFighter Generations-sandboxx.com

Definitions of Radar Key Terms:

PRT (Pulse Repetition Time) is the time interval between two consecutive pulses transmitted by a radar. It is also known as the pulse repetition frequency (PRF).PRI (Pulse Repetition Interval) is the time duration between the beginning of two consecutive pulses. It is the reciprocal of PRF.PRF (Pulse Repetition Frequency) is the number of pulses transmitted per second by a radar. It is the reciprocal of PRT.Pulse Group Repetition: Pulse group repetition in radars refers to the method of transmitting multiple pulses in a group, rather than transmitting them individually. In this method, several pulses are transmitted together in a group, followed by a pause before the next group is transmitted. The time between the transmission of two consecutive pulses within a group is known as the pulse repetition interval (PRI), while the time between the transmission of two consecutive groups is known as the pulse repetition time (PRT/PRF).Pulse group repetition is used to increase the radar's processing gain, which is the ratio of signal power to noise power. By transmitting multiple pulses in a group, the radar system can use the information from all of the pulses to improve the signal-to-noise ratio and increase the detection range. Additionally, pulse group repetition can be used to improve the range resolution of the radar system by increasing the number of pulses that are transmitted in a given time period.Pulse width (PW), also known as Pulse Duration (PD), is the length of time that a radar pulse is transmitted. It is the time interval between the start and end of the pulse. Pulse width is an important parameter in radar systems because it determines the energy of the pulse, the range resolution, and the sensitivity of the radar.A shorter pulse width results in a higher energy pulse, which can provide better range resolution and target detection at long distances. However, a shorter pulse width also results in a lower sensitivity, as the radar receiver has less time to integrate the signal.A longer pulse width results in a lower energy pulse, which can provide better sensitivity and target detection at short distances. However, a longer pulse width also results in a lower range resolution, as the radar cannot distinguish between targets that are close together.The choice of pulse width is a trade-off between range resolution and sensitivity, and is often determined by the specific application and requirements of the radar system.Azimuth Resolution is the ability of a radar system to distinguish between two objects that are in close proximity to each other in the horizontal plane. It is often measured in terms of the minimum angle between two objects that can be distinguished by the radar.Elevation Resolution is the ability of a radar system to distinguish between two objects that are in close proximity to each other in the vertical plane. It is often measured in terms of the minimum angle between two objects that can be distinguished by the radar.Range Resolution in radars refers to the ability of a radar system to distinguish between two or more targets that are located at different ranges, but at the same azimuth and elevation. This is an important characteristic of radar systems, as it determines the minimum distance between two targets that the system can distinguish. The range resolution of a radar system is determined by its pulse duration, or the time it takes for the radar to transmit a single pulse, and the pulse repetition frequency (PRF), or the rate at which the radar transmits pulses.
A radar system with a shorter pulse duration will have a better range resolution than one with a longer pulse duration. This is because a shorter pulse will have a narrower bandwidth, and will therefore be less affected by Doppler shifts caused by moving targets. Additionally, a radar system with a higher PRF will have a better range resolution than one with a lower PRF. This is because a higher PRF allows the radar to transmit more pulses in a given time period, providing more information about the target's range.
The range resolution of a radar system can be calculated using the following formula: Range resolution = c / (2 * Bandwidth)
Where c is the speed of light and Bandwidth is the pulse bandwidth. This formula shows that the range resolution is inversely proportional to the pulse bandwidth.
It's important to note that the range resolution of a radar system is also affected by other factors such as the signal-to-noise ratio and the environment, and that different types of radar systems have different range resolution characteristics. For example, pulsed radar systems have better range resolution than continuous wave radar systems. Additionally, radar systems that use synthetic aperture techniques, such as synthetic aperture radar (SAR), can have much higher range resolution than conventional radar systems.
In conclusion, range resolution is a critical parameter for radar systems and it is determined by the pulse duration, PRF, and pulse bandwidth. It is inversely proportional to the pulse bandwidth, the shorter the pulse duration and the higher the PRF, the better the range resolution. Other factors such as signal-to-noise ratio and environment also affect the range resolution.Radar Resolution Cell is the smallest volume in the radar's coverage area in which two or more targets can be distinguished by the radar. The resolution cell size is determined by the radar's range resolution, azimuth resolution and elevation resolution.

New Radar Techniques & Advancements

MIMO (multiple input, multiple output) radar: This technique uses multiple transmitters and receivers to increase the resolution and accuracy of radar systems.Cognitive radar: This type of radar uses machine learning algorithms to adapt to changing environments and improve target detection and classification.UWB (Ultra Wide Band) radar: Ultra-wideband radar uses very short pulses and a wide frequency range, which allows for high resolution and penetration through obstacles.Synthetic aperture radar (SAR): This technique uses the motion of the radar antenna to simulate a much larger aperture, which allows for high resolution imaging of the terrain.Inverse Synthetic Aperture Radar (ISAR): This technique is used to generate images of stationary or slowly moving objects, such as ships and aircrafts, using radar signals.Passive radar: This type of radar uses reflections from existing radio and television signals, rather than transmitting its own signals, making it difficult to detect.Multi-function radar: This type of radar system is designed to perform multiple functions, such as air and missile defense, early warning, and air traffic control, with a single system, which can be more cost-effective and efficient than having multiple systems.Metamaterial radar: This type of radar uses metamaterials, which are artificially engineered materials with unique electromagnetic properties, to improve the performance of radar systems. Metamaterials can be used to create ultra-wideband and highly directional antennas, which can improve the resolution and accuracy of radar systems.Millimeter-wave radar: This type of radar operates at very high frequencies, typically in the millimeter-wave range (30 GHz to 300 GHz), which allows for high resolution imaging and target detection. Millimeter-wave radar can also penetrate through some types of obscurants, such as dust, smoke, and light fog, making it useful for certain applications.Quantum radar: This type of radar uses quantum entanglement, a phenomenon in which two particles can be linked together so that the state of one particle affects the state of the other, to improve the sensitivity and resolution of radar systems. It is still in the early stages of research.
