Design and Performance Analysis of Transmitted Signal Waveforms with Spread Spectrum Technology for Netted Radar System

Lianqing Fu, Shizhong Yang, Tao Wang and Yaning Ma

Abstract:
In this study, the important function of netted radar system is discussed and its serious problem that mutual interference between transmitted signals, when it works in practice. In order to reduce the influence of mutual interference between signals, a novel netted radar system is designed. Transmitted signal of each station is assigned a unique Pseudo Noise (PN) code and all the PN codes from different stations are orthogonal. Because of the good autocorrelation and cross-correlation properties, mutual interference becomes weaker and signals from different stations could be separated by the preassigned PN codes and several radar stations can be active simultaneously. At the same time, the spectrum of the emission signal is spreaded, the Peak-to-mean Envelope Power Ratio (PMEPR) and the intercepted probability of the signals descend therefore. Simulation results show the good performance of the proposed approach and real radar system's detect result confirms the proposal.
