摘要

摘要: 在电子系统中，有时需要在同一平台上实现同时进行信号的接收和发射。这时，通常会采用一定的收发隔离措施和信号相消处理技术。相对于收发非同时而言，收发同时会对电磁频谱控制区域产生较大的影响。该文以同时接收雷达信号又干扰该雷达的情况为例，研究了收发同时对电磁频谱控制区域的影响，提出了综合天线收发隔离与后续数字相消处理的总体隔离度概念，分析了影响总体隔离度的因素，建立了数学模型，推导了相关公式，仿真分析了总体隔离度对侦察作用区、干扰暴露区以及电磁频谱控制区的影响。

Abstract: In the electronic system, it occasionally needs to accomplish the transmission and reception of signal in the same platform, at this time, certain transceiver isolation and signal cancellation processing technology are usually adopted. Relative to non-simultaneous transmission and reception, simultaneous transmission and reception makes more influence on electronic warfare area. This paper takes the situation of receiving the radar signal and interfering in itself for example, makes the research of the effect of simultaneous transmission and reception on electronic warfare area. The conception of total isolation of comprehensive transceiver antenna and follow-up digital cancellation is proposed in the paper, and the factors that affect the total isolation are analyzed, then the mathematical model is set up, and the correlative formulas are deduced. In the end, the influence of total isolation on the reconnaissance function area, jamming exposure area and comprehensive electronic warfare area are analyzed by simulation.
