摘要
为评估机载雷达性能需要研制杂波模拟器,采用软件硬件相结合的方法,根据机载雷达杂波相干模型产生杂波模拟基带数据,将该数据传送给模拟器,由模拟器将基带杂波数字信号进行数字上变频并转换为中频模拟信号;该模拟器能够根据不同的设置参数生成符合要求的功率谱特征和信号幅度分布特征的杂波模拟信号,其实测结果和仿真结果相一致;该模拟器设计简单、灵活,通用性强,为机载雷达杂波的模拟和工程实现提供了可行的方法。
In order to evaluate the property of airborne radar,it needed to develop clutter simulator,which can be applied by combining software and hardware methods.The simulated clutter base-band data will be transmitted into the simulator,according to which generated by the coherent airborne radar clutter model.In addition,the simulator provides digital up-conversion to base-band clutter data,and turns the data into IF signal.The simulator generates simulated clutter signal according to different parameters setting.The simulated clutter signal is satisfactory with the power spectrum feature and signal amplitude distribution characteristics,and the testing result is same as simulation result.This simulator is simply designed,flexible,and with strong versatility,providing a possible method for the simulation and project realization of airborne radar clutter.
