| 摘 要： | 根据二维相位和差单脉冲雷达系统实现结构,分析和仿真了天线-和差器、和差器、通道处理3部分电路的不理想对测角性能的影响.结果表明,天线-和差器的幅度不一致影响测角大小,相位不一致影响测角大小和测角极性;和差器阻抗不匹配影响测角大小和极性;通道处理电路幅度不一致影响测角大小,相位不一致影响测角极性.在不理想因素中,天线-和差器相位不一致对测角性能的影响最小,天线-和差器幅度不一致以及和差器阻抗不匹配的影响较大.

| Abstract: | According to the structure of sum-difference patterns phase-comparison two-dimension mono-pulse radar system,the system is divided into three parts,including the antenna-comparator,comparator,and channel processing circuitry.The impact of their non-ideal to the performance of angle measurement is analyzed and simulated.Some meaningful conclusions are acquired.The amplitude imbalance of antenna-comparator has influence on measured angle value but sign,and the phase imbalance has influence on both the measure... |
