Two-step algorithm of location-weighing in radar with long signals

The two-step algorithm for radar sounding in millimeter wave band with quasi-continuous signals, is proposed. On the first step the sounding is conducted by the non- modulated pulse, and it serves to detect the targets and estimate their radial velocities. This estimation results is used for tuning the optimal filters on Doppler frequencies of the received signal. The distances to the detected targets are measured by the phase-modulated signal at the second step of the observation. Due to preliminary estimation of the velocity, the multitude of Doppler channels which bars from application of the signals with large base in millimeter band radars, is excluded.
