WebAn unmodulated continuous wave radar emits a constant frequency with constant amplitude. The received echo signal either has exactly the same frequency, or the echo signal is shifted by the Doppler frequency (with a reflector moving at a radial velocity). CW radars that specialize in measuring this Doppler frequency are called Doppler radars. WebAug 2, 2024 · FM continuous wave radar refers to a continuous wave radar whose transmitting frequency is modulated by a specific signal. The principle of frequency modulated continuous wave (FMCW) radar is to send a continuous signal with a certain bandwidth and linear change in frequency, and then perform fast Fourier transform on …
