The first operational pulse-Doppler radar was in the CIM-10 Bomarc, an American long range supersonic missile powered by ramjet engines, and which was armed with a W40 nuclear weapon to destroy entire formations of attacking enemy aircraft. [1] Pulse-Doppler systems were first widely used on fighter aircraft starting in the 1960s. Earlier ...
Pulse Doppler radar may have 50 or more pulses between the radar and the reflector. Pulse Doppler relies on medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. Each transmit pulse is separated by 5 km to 50 km distance. Range and speed of the target are folded by a modulo operation produced by the sampling process.
The most effective clutter reduction technique is pulse-Doppler radar with Look-down/shoot-down capability. Doppler separates clutter from aircraft and spacecraft using a frequency spectrum, so individual signals can be separated from multiple reflectors located in the same volume using velocity differences. This requires a coherent transmitter.
The pulse width is related to the time-on-target, the signal-to-noise ratio (SNR) and the maximum range. The instantaneous signal bandwidth is related to the range resolution. Pulse-Doppler processing: Echoes originating from a radiated burst are transformed to the spectral domain using a discrete Fourier transform (DFT). In the spectral domain ...
Range ambiguity resolution is a technique used with medium pulse-repetition frequency (PRF) radar to obtain range information for distances that exceed the distance between transmit pulses. This signal processing technique is required with pulse-Doppler radar. [1] [2] [3]
The AN/APG-68 radar is a long range (Max Detection Range 80 kilometres [50 mi]) [2] Pulse-Doppler radar designed by Westinghouse (now Northrop Grumman) to replace AN/APG-66 radar in the General Dynamics F-16 Fighting Falcon. The AN/APG-68 radar is now currently being replaced on US Air Force F-16C/D Block 40/42 and 50/52 by the AN/APG-83 AESA ...
The JL-10A airborne radar is a highly digitized pulse-Doppler radar with slotted planar array developed for the People's Liberation Army Air Force (PLAAF) as a replacement for the older Type 232H radar currently employed by the Chinese air force.
Pulse-Doppler radars combine all the benefits of long range and high velocity capability. Pulse-Doppler radars use a medium to high PRF (on the order of 3 to 30 kHz), which allows for the detection of either high-speed targets or high-resolution velocity measurements.
