The paper focuses on the problems of the use of pseudonoise phase modulation broadband signals in the radar survey. The average correlation characteristics of these signals in the Doppler frequency range and the structure of the processing system, including a multi-channel frequency matched filter, are determined. Methods of protecting the signal detection systems from the effects of narrow-band impulse and passive interference are proposed
