Individual objects can be detected using the Doppler effect, which causes the received signal to have a different … See more The main advantage of CW radar is that energy is not pulsed so these are much simpler to manufacture and operate. They have no minimum or maximum range, although the broadcast power level imposes a practical … See more There are two different antenna configurations used with continuous-wave radar: monostatic radar, and bistatic radar. Monostatic The radar receive … See more 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 … See more • Luck, David G.
