Radars can use this frequency/phase shift as an excellent tracking method and ECCM. The period (wavelength) of 20 kHz is 200 microseconds. To recover this 20 kHz shift from the original radar signal, the original must be CW or a pulse train with pulses of a period several times longer than 200 microseconds (a "pulse Doppler" radar). ................
