A radar receiver and, more particularly, a radar receiver of the type which is utilized in connection with a frequency-modulated, continuous-signal radar apparatus. The radar receiver, in the receiving channel thereof, is provided with a high-pass filter of the second order which is only operated in the linear characteristic curves range, thus acting as an R4-filter and which is connected in front of a demodulating rectifier, or in essence, an analog-digital quantitizer.
