  • 摘要: 在電子系統(tǒng)中，有時需要在同一平臺上實現(xiàn)同時進行信號的接收和發(fā)射。這時，通常會采用一定的收發(fā)隔離措施和信號相消處理技術(shù)。相對于收發(fā)非同時而言，收發(fā)同時會對電磁頻譜控制區(qū)域產(chǎn)生較大的影響。該文以同時接收雷達信號又干擾該雷達的情況為例，研究了收發(fā)同時對電磁頻譜控制區(qū)域的影響，提出了綜合天線收發(fā)隔離與后續(xù)數(shù)字相消處理的總體隔離度概念，分析了影響總體隔離度的因素，建立了數(shù)學(xué)模型，推導(dǎo)了相關(guān)公式，仿真分析了總體隔離度對偵察作用區(qū)、干擾暴露區(qū)以及電磁頻譜控制區(qū)的影響。
    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.
