摘要

摘要: 外輻射源雷達(dá)網(wǎng)絡(luò)的探測性能受網(wǎng)絡(luò)幾何架構(gòu)、電波傳播環(huán)境、硬件系統(tǒng)性能及信號和數(shù)據(jù)處理能力等諸多因素的影響，網(wǎng)絡(luò)優(yōu)化部署需綜合考慮上述各個方面，網(wǎng)絡(luò)性能評估為需要解決的首要問題。該文圍繞外輻射源雷達(dá)網(wǎng)絡(luò)定位性能展開，首先給出一種切實(shí)可行的外輻射源雷達(dá)網(wǎng)絡(luò)優(yōu)化系統(tǒng)定位性能評估方案，利用蒙特卡洛仿真分析了一定站位配置下定位精度分布圖。接著重點(diǎn)介紹了外輻射源雷達(dá)組網(wǎng)探測實(shí)驗(yàn)開展情況，包括系統(tǒng)配置、空中目標(biāo)探測典型結(jié)果及分析。最后統(tǒng)計評估了實(shí)測目標(biāo)的定位精度，并與仿真結(jié)果進(jìn)行對比，從實(shí)驗(yàn)角度驗(yàn)證了定位性能評估方案的有效性。

Abstract: Detection performance of Passive Radar Network (PRN) is affected by many factors including network geometry, radio propagation environment, performance of system, signal and data processing capability, and so on. Optimized disposition with passive radar network needs to consider all the aspects, and performance evaluation of the network should be firstly taken into consideration. Launching from the positioning performance of passive radar network, first a feasible evaluation scheme is proposed, and the distribution of positioning precision is obtained by Monte-Carlo simulation under a specified network configuration. Then, the experimental scenario and the experimental progress is highlighted, involving system introduction, illustration, and analysis of typical detection results of airplanes. Finally, the positioning accuracy is compared with reference information and simulation results, which proves the validity of passive radar network positioning performance evaluation scheme.
