摘　　要：预警机组成编队时不同平台上的预警雷达间可能会有干扰产生,因此需要研究预警机编队雷达电磁兼容问题;在分析预警机作战运用的基础上,建立了预警雷达在复杂电磁环境下的互扰模型,分别从干扰功率和探测距离两个方面对预警雷达相互干扰做了定量的分析,给出了预警雷达干扰计算方程并进行仿真验证;该模型能够在不需要设备进行试验的情况下对预警雷达之间以及同其他用频装备的干扰进行预测评估,从而对预警机的运用和电磁频谱管理提供有力的保障,保证预警雷达作战效力的发挥。A imperative is to study the compatibility issues existing in airborne early warning radars as AWACS coming into formation , which is especially important when mutual interference is induced by the airborne early warning radars in different platforms. Based on the analysis of the applications of AWACS , the model on the operation of early warning radars under the conditions of complicated electromagnetic environment is established . Also, this model gives a quantitative analysis on the mutual interference of airborne early warning radars in terms of interference power and detection distance, which proposes calculation equations of airborne early warning radar. Based on that, simulation verification is conducted at the end. The study model established in this text can forecast and evaluate the mutual interference among airborne early warning radars and other device with frequency without site test. Furthermore; this study can provide efficient safeguard for the application of airborne early warning radars and management of electromagnetic Spectrum to assure the particular function of airborne early warning radars.
