基于GPS照射源的双基地新体制雷达探测系统

摘要

基于GPS导航卫星的双基地雷达由于其良好的隐蔽性、反隐身能力以及抗干扰能力，简单的系统结构，低廉的造价等优点，近年来在国内外掀起了新的研究热潮。然而由于辐射源功率以及系统结构的原因，传统的双基地雷达系统接收信号的信噪比较小，很难检测到目标。本文提出基于导航卫星多发单收的双基地雷达系统，相比于传统的双基地雷达信号检测信噪比有明显的改善。%Bistatic radar Based on GPS navigation satellite have the advantages of good concealment, anti-stealth and anti-interference ability, simple system structure at low cost, which raised a new research upsurge at home and abroad in recent years. However, the traditional bistatic radar system has low signal noise ratio (SNR) signals because of the power of illumination and the structure of the system, which make it difficult to detect targets. A new bistatic radar system based on the navigation satellite is developed in this paper. And comparison between the traditional bistatic radar shows that signal detection of noise ratio is obviously improved.
