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.
