The home-made APS has been produced and tested based on the pulse-doppler radar
system and its weapon is also of firewall type.
Fathy, "CW and pulse-Doppler radar
processing based on FPGA for human sensing applications", IEEE Trans.
uses radio waves to register atmospheric activity and energy, such as precipitation, storms, and fog.
The Sanders ALQ-156 uses pulse-Doppler radar
to detect approaching missiles by measuring closure rates and other ballistic parameters, and activates counter-measures.
We evaluate the performance of the hybrid UWB pulse generator for a 24 GHz UWB pulse-Doppler radar
by combining a digital pulse and a 24 GHz RF transmitter.
The EL/M-2160 is a pulse-Doppler radar
that detects incoming missiles.
The Erieye is an integrated AEW&C system that includes an active, phased-array, pulse-Doppler radar
integrated with electronic-support measures, communications and datalinks, command-and-control facilities.
It includes new displays, the Phazotron N010 Zhuk pulse-Doppler radar
, the RC 400 multifunction radar, a laser-designator and targeting pod, and a forward-looking infrared (FLIR) sensor.
This is an active, pulse-Doppler radar
system with three antennas -- two in the wing roots and one in the tail.
The upgraded AN/SPQ-9B will use a high-resolution, track-while-scan, X-band, pulse-Doppler radar
and will maximize the use of in-service and commercial off-the-shelf/non-developmental-item (COTS/NDI) equipment.
As shown in Figure 4, the pulse-Doppler radar
outputs a coherent pulsed signal with a high duty factor.
The duty cycle [pulse duration/pulse interval] of a regular pulse radar (as opposed to a pulse-Doppler radar
) is typically of the order of 0.1 percent.
