Pulse Radar is use for detecting of target location . and CW Radar stands for continuous wave radar. Here is difference between Pulsed RADAR and CW RADAR. Pulsed RADAR : In this system the pulse modulated signal are used for transmission.28 Oca 2011
Read moreWhat are limits of CW radar?
Unmodulated continuous wave radar cannot measure distance . Signal amplitude provides the only way to determine which object corresponds with which speed measurement when there is more than one moving object near the receiver, but amplitude information is not useful without range measurement to evaluate target size.

Disadvantages of CW Doppler Radar
Read moreWhat are the advantages and disadvantages of CW radar?
Benefits or advantages of CW Radar ➨It is used for wide variety of applications as listed above. ➨It transmits power with lower value and hence does not interfere other wireless devices . ➨It is simple in construction. ➨The performance of CW radar is not affected due to stationary targets.
Read moreWhich of the following is the biggest disadvantage of the simple CW radar?
One of the greatest shortcomings of the simple CW radar is its inability to obtain a measurement of range . This limitation can be overcome by modulating the CW carrier, as in the frequency-modulated radar.
Read moreWhat is the principle of FM radar?
The radar principle used is FMCW (Frequency Modulated Continuous Wave) . The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected from the measuring surface and received with a time delay, t.
Read moreWhy CW radar can measure range?
CW radar can measure the instantaneous rate-of-change in the target’s range. This is accomplished by a direct measurement of the Doppler shift of the returned signal . The Doppler shift is a change in the frequency of the electromagnetic wave caused by motion of the transmitter, target or both.
