| 摘 要： | 对AN/TPY-2雷达作用距离研究的目的是分析雷达的工作性能以及建立仿真平台以研究干扰其的方法。首先,利用雷达方程推导了不同雷达截面积(radar cross section,RCS)、信噪比、脉冲累积个数下的雷达最大作用距离。信噪比为5时,前置模式(RCS=10 m2)和末端模式(RCS=0.1 m2)时,作用距离分别约为3 735 km和834 km。其次,针对威胁较强的前置模式,提出使用电子干扰的对抗措施以降低雷达的检测性能。最后,基于SystemVue软件建模了雷达电子干扰系统,对不同信干比条件下的雷达检测概率进行了验证。仿真显示电子干扰能够明显降低该雷达的探测性能。

| Abstract: | The purpose of the research on radar range is to analyze AN/TPY-2 radar’s operating performance and build a simulation platform to analyze jamming methods. Firstly, using radar equation, the maximum range of radar based on radar cross section (RCS), signal to noise ratio and cumulative number of pulses are derived. When the signal-to-noise ratio is 5, the distances for the front-basedmode (RCS is 10 m2) and the terminal-based mode (RCS is 0.1 m2) are about 3 735 km and 834 km, respectively. Secondly, considering stronger threat caused by the front-based mode radar, electronic jamming countermeasures are used to decrease radar’s detection performances. Finally, based on the SystemVue software, the radar electronic countermeasure system is modeled, and radar detection probabilities under different signals to interference ratio conditions are verified. The simulation results show that the electronic jamming can significantly reduce the detection performance of the AN/TPY-2 radar. |
