With the advent of digital techniques, Pulse-Doppler radars ( PD ) became light enough for aircraft use, and doppler processors for coherent pulse radars became more common.
22.
Because of the low pulse repetition frequency ( PRF ) of most coherent pulsed radars, which maximizes the coverage in range, the amount of Doppler processing is limited.
23.
The FMCW ramp can be compressed providing extra signal to noise gains such one does not need the extra power that pulse radar using a no FM modulation would.
24.
Signals from Doppler pulse radar, installed in 1995, are processed by software that gives readings precise enough to distinguish between parts of a missile that breaks up in flight.
25.
This was handled by the truck-mounted Type 83 " Yellow River " pulse radar system that could be fairly easily jammed and was vulnerable to ground'clutter', thus degrading low-level capability.
26.
Although the U . S . had developed pulsed radar independently of the British, there were serious weaknesses in America's efforts, especially the lack of integration of radar into a unified air defense system.
27.
The AN / SPS-67 ( V ) 1 radar is a two-dimensional ( azimuth and range ) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection.
28.
His invention of the line type pulse modulator ( ref vol 5 of MIT Radiation Laboratory series ) was a major contribution to high-powered pulse radars, not just the H2S's system, and continues to be used today.
29.
When the exchange began, the British were surprised to learn of the development of the U . S . Navy's pulse radar system, the CXAM, which was found to be very similar in capability to their Chain Home technology.
30.
By order of the German navy, in the summer of 1935 they developed a pulse radar with which they could spot the cruiser " K�nigsberg " at a distance of 8 km, with an accuracy of up to 50 m, enough for gun-laying.
