摘要
采用变调制恒差频方法的线性调频准连续波(LFMICW)雷达高度计,需要实时的根据差拍信号的频率来改变发射信号的波形。差拍信号的计算需要快速傅里叶变换,运算量大。为了实现高度计对高度的搜索与跟踪,需设计相应的搜索与跟踪算法。针对信号处理算法及系统对实时性的要求,设计了专用的信号处理平台,实现了高度计的信号处理。
By changing the parameters of the transmission signal to obtain the invariable beat signal, LFMICW radar altimeter need to change transmission signal waveform depending on the beat signal frequency in real-time. According to the real-time requirements of signal processing algorithms and system a dedicated signal processing processor is designed for signal processing of Altimeter.
