Abstract

Radar sensors are wide spread as ranging and navigation systems, especially in ATC and prevention of wings’ collisions. Traffic handing on routes and commuter areas is held with their use. Therefore, improving the noise immunity of radar sensors remains as priority, especially in aviation sector. In this connection, we consider a synthesis method of complex signals with irregular bi-level structure envelope of power spectrum. We conducted analysis of synthetic signal’s spectral characteristics. We described the possibility of the use of such signals for frequency clutter rejection localized in a relatively small range of Doppler frequency shifts. The frequency rejection of ground reflection is proposed to improve the noise immunity of radar sensors.
