基于OFDM-MIMO的抗单比特接收机低截获雷达信号设计
OFDM-MIMO based low intercept radar signal design for anti monobit receiver
摘要
Abstract
In comparison with the traditional electronic warfare frequency measurement receivers,digital receivers focus their signal detection process on the level of digital signals and have a high system integration.Thanks to the huge advantages demonstrated in detecting multiple simultaneous signals,they have received widespread attention.This article takes a typical monobit digital receiver as the research object to enhance the survivability of our own radar on the battlefield and effectively counter the reconnaissance of enemy broadband digital receivers.By analyzing the frequency measurement principle and taking the limitations of multi signal detection caused by monobit sampling in signal processing as the starting point,an OFDM-MIMO broadband low interception radar signal based on signal amplitude modulation is designed.The simulation and experimental results show that the designed radar signal has high complexity in the frequency domain and can effectively counter the monobit receiver reconnaissance based on frequency detection of signal spectrum peaks.The interception probability of the monobit receiver on the designed signal is only 20%,so the signal has good low interception characteristics.关键词
