|
摘要
基于弹载雷达系统高精度目标信息测量的性能需求,本文提出对FFT频谱数据检测结果采用扩展比值插值算法进行处理,以减少目标速度信息测量误差。仿真试验验证了该方法对提高测量精度的有效性,该方法在实际应用中实现了高精度目标信息测量,从而为提高弹载雷达系统性能、实现对目标的精确跟踪提供有力技术基础。
Based on the capability requirement about high accuracy measurement on taget velocity, this paper presents a method that using the expanded ratio and interpolation algorithm after the FFT frequency detection in order to reduce velocity measurement error. This method"s efficiency on improving measurement precision is demonstrated via alrithom simulation,And it is used in a factual radar system,achieving high accuracy target information measurement.So,this method is propitious to improve the capability of the missile-borne radar with regard to actualize precision target tracking.
