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.

Continuous-wave radar maximize total power on a target because the transmitter is broadcasting continuously.

A second limitation for hand-held devices is that they have to use continuous-wave radar to make them light enough to be mobile.

Maximum distance in a continuous-wave radar is determined by the overall bandwidth and transmitter power.

Neither of these present a problem for continuous-wave radars, nor for microwave ovens.

Feed-through null follows the duplexer and is commonly used with continuous-wave radar to improve performance.

Semi-active missile systems use bistatic continuous-wave radar.

Alternatively, Frequency Modulated Continuous-wave radar can be used.

Pulse-Doppler radar and Continuous-wave radar are required for high performance in this area because these exclude low-velocity reflections.

There are two types of continuous-wave radar: unmodulated continuous-wave and modulated continuous-wave.

Continuous-wave radar (non-pulsed, pure doppler processing)

There are two different antenna configurations used with continuous-wave radar: monostatic radar, and bistatic radar.

It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics.

A continuous-wave radar system is one where a continuous wave is transmitted by one aerial while a second aerial receives the reflected radio energy.

Continuous-wave radar is a type of radar system where a known stable frequency continuous-wave radio energy is transmitted and then received from any reflecting objects.

Modern SARH systems use continuous-wave radar (CW radar) for guidance.

Frequency-modulated continuous-wave radar (FMCW)

Continuous-wave radar without FM modulation only detects moving targets, as stationary targets (along the line of sight) will not cause a Doppler shift.

The MK 74 MOD 15 configuration includes continuous-wave radar tracking in addition to pulse-Doppler tracking.

Continuous-wave radar may be aimed directly at a vehicle 100 yards away but produce a speed measurement from a second vehicle 1 mile away when pointed down a straight roadway.

The attack radar featured a Doppler beam-sharpening, moving target indication (MTI), and Continuous-wave radar for guiding semi-active radar homing missiles.

It is possible to make a Doppler radar without any pulsing, known as a continuous-wave radar (CW radar), by sending out a very pure signal of a known frequency.

The final service version, the mod 3, was a true semi-active radar homing (SARH) missile with a continuous-wave radar receiver built into the missile, which homed in on the CW radar return of the illumination radar.

After its mid-life upgrades, which shared several components with the RAF's Bristol Bloodhound, Thunderbird featured a continuous-wave radar semi-active homing system that was highly resistant to Radar jamming and deception, and was able to track targets even at very low altitudes.

On the formation of the British Aircraft Corporation Bristol had joined as a junior partner, with all guided weapon work assigned to English Electric, whose guided weapon team had commenced the development of a weapon with second generation continuous-wave radar (CW) guidance.
