摘要
提高雷达模拟器生成回波信号的真实性和可靠性,需要实时采集一些重要的雷达工作状态参数,如雷达工作时的天线方位角和高低角信号、主脉冲信号、锥扫基准信号和载波频率信号等。这些信号分别为模拟回波信号的生成提供了天线增益大小、时间基准、相位基准和载波频率大小等重要的参考信息。通过对这些信号性能参数的分析和研究,提出模拟器与雷达系统接口电路设计方案。雷达实验可以证明该设计性能稳定、可靠、成本较低,很好地实现了接口电路的功能要求。
Some necessary working state parameters of radar need to be collected real-timely,（such as the azimuth angle of antenna,the high-low angle signal,the signal of main plus,the normal signal of taper scan and the signal of carrier wave frequency and so on） in order to improve the echo of radar simulator＇s facticity and reliability.These signals provide an important reference of the gain of antenna,the time reference,the phase reference and the frequency of carrier wave for generating stimulant echo signal.The design scheme of interface circuit between radar simulator and radar is proposed through analyzing and studying the performance parameter of signals.The experiments show that the design is steady,reliable and low-cost,and achieves the functional demand of the interface circuit.
