Experimental Estimation of the Projection Method of the Doppler Filtering of Radar Signals when Detecting Air Objects with Low Radial Velocities

  • Published:
Radiophysics and Quantum Electronics Aims and scope

We present experimental results of using the projection method of the Doppler filtering of radar signals to detect low-speed air targets against the background of intense reflections from local objects. The possibility is shown of synthesizing filters with different widths of the frequency-response stopband, which ensure detection of low-speed targets against the background of reflections from local objects in a given range of radial velocities. The dependence of the transmission coefficients of a useful signal on its Doppler frequency is analyzed for various values of both the number of pulses in a burst of received signals reflected from the target and the Doppler-filter parameters (the number of zeros of the frequency-response stopband).
