雷达模拟器中杂波信号的逼真程度对雷达职手的训练质量起着至关重要的作用。如果海杂波和气象杂波的数学模 型产生的模拟信号不够逼真,就无法满足雷达职手的训练要求。文中根据训练态势中设定的自然环境条件,对外场实验 中采集到的真实杂波数据进行位置和强度上的处理,从而产生满足战术训练要求的海杂波和气象杂波信号。由雷达模拟 器的终端显示可知,该方法产生的海杂波和气象杂波信号具有很高的逼真度,可以满足雷达职手的训练需要。

The fidelity of sea clutter and weather clutter in radar simulator is necessary to training quality. The fidelity of simulated clutter signal based on mathematics model is not good enough for radar operator忆s training. The real sea clutter and weather clutter data sampled were used to generate simulated clutter signal in this letter. The real clutter data sampled was processed based on natural condition in simulation situation to generate simulated echo signal which can satisfy the request of tactics training. The image of Radar display shows that the sea clutter and weather clutter signals generated by this method have high fidelity and can meet the demand of radar operator training.
