| 摘 要： | 对一种在单脉冲雷达中采用的以调相信号的频率压缩和合并通道中压缩信号的限幅为基础的通道合并定向接收机(角度鉴别器)进行了分析，建立了这种定向接收机在三通道幅相特性不平衡时的仿真用模型，应用这一模型可以分析接收机非线性、通道间耦合、和差通道幅相特性的不平衡等对单脉冲雷达定向特性的影响。

| Abstract: | In directional radar the directional characteristic is affected by nonideal sum and difference performance caused by small mismatch of microwave bridge port.The directional receiver(angle comparator) of monopulse radar is analyzed. The receiver is based on frequency compression of phase modulation and amplitude limit of compression signal in combining channel. The simulation model of amplitude-phase imbalance for the receiver is established . The model is used to evaluate the impact of no-linearity of receiver, channel coupling, amplitude-phase imbalance among sum-difference channels on monopulse radar directional performance. |
