The Use of Phase-shift Keyed Signals with a Zero Autocorrelation Zone in a Multi-position Radar System for Searching and Detecting of Space Debris Objects

To provide highly accurate data on the range, velocity and angular coordinates of space debris objects, the phase-shift keyed (PSK) signal with a zero autocorrelation zone with a large compression ratio of several thousand is used, which ensures a low level of side lobes of the autocorrelation function of the signal and, accordingly, a low level of correlation noise, with a fairly accurate predicted Doppler shift.
