continuous wave radar
CW radar

The transmitter is constantly issuing high power RF with continuous wave radar.

Operators cannot be certain which object's speed the device has measured without distance information, which is unavailable with continuous wave radar.

Meanwhile the much improved continuous wave radar systems being developed for the same project, Green Sparkler, were progressing quite nicely.

This technique can be used in continuous wave radar and is often found in aircraft radar altimeters.

Continuous wave radars rely on the Doppler effect to detect moving targets, comparing returned signals to the reference signal being broadcast.

Feed-through nulling significantly reduces the bleed-through signal, which can be used to increase receiver sensitivity in continuous wave radar.

Unmodulated continuous wave radar cannot measure distance, and the beam is usually broad with side-lobes that extend to the side and behind the radar antenna.

FAAD used a continuous wave radar, which uses the Doppler shift of the moving targets to locate them against any sort of background.

The radar warning receiver detects pulse-Doppler, pulse and continuous wave radar threats and provides threat identification by comparing signal characteristics against a threat database.

The stations consisted of a module train, a warehouse, a vehicle garage, an Inuit house, POL (Petroleum, Oil, Lubricant) tanks and a continuous wave radar tower.

In the meantime, advances in radar technology were proceeding rapidly, so it was decided to produce interim designs using new continuous wave radars which would dramatically improve the performance of the existing missiles.

An unmodulated continuous wave radar has no range resolution, but can resolve targets on the basis of different velocity, while a modulated or pulsed radar can resolve echoes from different ranges.

The 9K37 system can also utilise the same 1S91 Straight Flush 25 kW G/H band continuous wave radar as the 3M9 "Kub" system.

Very similar frequency swept waveforms are used in frequency modulated continuous wave radars to measure range (distance); an unmodulated continuous wave Doppler radar can only measure range-rate (relative velocity along the line of sight).

A MPQ-61 HIPIR radar provides low altitude and local area radar coverage as well as continuous wave radar illumination for the MIM-23K Hawk missilles.

COUNTERMEASURES The countermeasures suite includes an AN/ALQ-144 infrared jammer, radar warning receivers against pulsed and continuous wave radars and a laser warning detector.

Four 12V 7 Ah batteries are divided into two banks; two in parallel supplying 12V circuits redundantly, and two in series for the 24V Weibel radar transponder sending to a Continuous Wave radar on the deck of Hjortø.
