【摘要】 在雷达侦察系统中,为了能够在复杂的电磁环境中实现对雷达进行准确识别和定位,设计了基于中频数字化平台,对输入的脉冲包络信号在现场可编程门阵列中实现其参数测量,避免使用乘法器等需要占用大量资源的模块,节约硬件资源的同时也缩短了运行时间,具有良好的实时性和较高的测量精度,可以用于后续DSP算法实现对目标雷达的识别和定位。更多还原

【Abstract】 A new design in radar reconnaissance system was developed for real-time measuring the waveform parameter of the pulse envelop launched by radar system from the enemy side.The design is developed based on intermediate frequency digital platform and provides high measurement accuracy.In addition,the design does not need resource-cost elements,for example multiplier,thus the operation time is effectively shortened and the function of real-time measuring the wave parameter of the input wave envelop in FPGA can be realized.Owing to these advantages,the proposed design can be used for latter DSP arithmetic design,which aims at identifying and orienting target radar.更多还原
