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 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 is the advantage of FMCW radar?
Benefits or advantages of FMCW Radar ➨It uses low power for transmission . This can be supplied by many solid state devices such as magnetron, BWO, reflex klystron etc. ➨The super-heterodyne based architecture delivers good sensitivity and stability. ➨It offers higher bandwidth compare to CW radar.
Read moreWhat is the principle of FMCW 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 moreWhat’s the difference between FMCW and CW radars?
If CW Doppler Radar uses the Frequency Modulation, then that Radar is called FMCW Doppler Radar or simply, FMCW Radar . It is also called Continuous Wave Frequency Modulated Radar or CWFM Radar. It measures not only the speed of the target but also the distance of the target from the Radar.
Read moreWhat is FMCW used for?
Radar systems measure the time of flight from when a transmitted signal leaves the radar, hits a reflecting target and returns to the radar .
