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.
Read moreHow does a CW radar work?
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.
Read moreHow does CW radar work?
Continuous-wave radar (CW 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 .
Read moreWhat are the limitations of CW radar?
Disadvantages:
Read moreWhat is continuous wave radar used for?
The Radar, which operates with continuous signal (wave) for detecting non-stationary targets , is called Continuous Wave Radar or simply CW Radar. This Radar requires two Antennas. Among which, one Antenna is used for transmitting the signal and the other Antenna is used for receiving the signal.
Read moreWhat is the principle of CW radar?
Principle of Operation. 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 moreWhat is the difference between pulse radar and continuous wave radar?
Pulsed signals remain powered for short periods of time, working with and without some form of modulation, such as amplitude, frequency, or phase modulation. CW signals remain on constantly and may be modulated to function as radars or in communications systems.
