Signal constructions with low resultant sidelobes for pulse compression navigation and radar systems

摘要

The pulse compression technology and related signal constructions are widely used in navigation (e.g., Gold codes with low sidelobes of periodic cross-correlation function) and radar systems (e.g., Barker or other sequences with low sidelobes of autocorrelation function). A signal in a pulse compression system may consist of some signal components which along with their joint signal processing make possible to obtain a signal with a low sidelobe level at the output of signal processing system. Such signal constructions, which are based on the binary sequences of different lengths, and also their joint signal processing are done in the paper. It is established that they make possible to obtain the maximum sidelobe level after signal processing -26.02-6.02(K-2) dB, K > 1, where K is the number of signal components (binary sequences) in a signal construction.
