Following are the disadvantages of radar: ➨It can not distinguish and resolve multiple targets which are very close like our eye . ➨It can not recognize color of the targets. ➨It can not see targets which are in the water and are too deep.
Read moreWhy can’t a CW radar measure range What is the main advantage of a CW radar?
As opposed to pulsed radar systems, continuous wave (CW) radar systems emit electromagnetic radiation at all times. Conventional CW radar cannot measure range because there is no basis for the measurement of the time delay .
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 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 moreWhat are the applications of CW radar?
A continuous wave (CW) radar has been used for the detection and classification of people based on the Doppler signatures they produce when walking . When humans walk, the motion of various components of the body including the torso, arms, and legs produce a very characteristic Doppler signature.
