continuous-wave radar

[kən¦tin·yə·wəs ¦wāv ′rā‚där]
(engineering)
A radar system in which a transmitter sends out a continuous flow of radio energy; the target reradiates a small fraction of this energy to a separate receiving antenna. Also known as continuous-wave Doppler radar.

Another highlight is a 79 GHz binary phase-modulated continuous-wave radar transceiver with TX-to-RX spillover cancellation in 28nm CMOS (developed together with Panasonic), and a flexible thin-film NFC tag powered by a commercial USB reader device at 13.
9 V and an output power above 10 dBm, the continuous-wave radar transmitter operates in the 79-GHz band.

used its microwave power module and digital RF technology to assemble the Tactical Radar Jammer (TRJ), designed to counter pulse, pulse-Doppler and continuous-wave radar threats.
As outlined to JED, the DAS comprises Litton's ALR-69 RWR, Elta's EL/M-2160 pulse Doppler missile approach warner, two Northrop Grumman ALQ-162 continuous-wave radar jammers and a Danish-developed chaff/flare dispensing subsystem.
For the international market, Litton has formed the Integrated Helicopter EW System (IHEWS) alliance, offering customers a "one stop" defensive aids package which can be "mixed and matched" from the already noted US Army AH-1/AH-64 equipment plus the ALQ-162 continuous-wave radar jammer, the AVR-2 laser warner and the ALE-47 "smart" dispenser.
As JED understands it, IHEWS incorporated the Litton Pegasus radar warning receiver (RWR), ITT's AN/ALQ-136 pulse radar jammer, Northrop's AN/ALQ-162 continuous-wave radar jammer, a variant of Lockheed-Sanders' AN/ALQ-144 fixed-source infrared jammer, Tracor's "threat adaptive" AN/ALE-47 decoy dispenser and Hughes' AN/AVR-2 laser warner.
The system identifies the types of radar threats, measures the threat parameters and then uses the transmitters to jam both pulse and continuous-wave radars, while control features ensure that home-on-jam weapons are not allowed enough time to acquire the aircraft.
Low-power continuous-wave radars, for example, can be confusing: is it a radar or a communications signal?
