查询词典 ranging

multi-channel correlators are widely used in traditional pseudo-random code cw radar,which makes the ranging system more complicated.this paper proposes a method of digitalizing the return signal directly and then convoluting the signals on dsp,which can replace multi-channel correlation in analog circuit.but the computation of convolution is too huge for the dsp to fulfill.to solve this problem,this paper analyzes five fast algorithms including fft,and then chooses one according to the characters of prc-cw radars.the digital method and fast algorithm have been verified by simulated signal and real signal.

一种提高空间伪码扩谱测距精度的实用。。。摘要：传统的伪码调相连续波雷达采用多路模拟相关电路实现对回波信号的相关接收，通过多路试探搜索各距离单元的目标，电路复杂。提出的数字化方案，对回波信号直接数字化，利用高速dsp实现数字卷积，可替代多路模拟相关电路。但是直接卷积的运算量过大，dsp无法承受。本文对此进行了研究，分析了包括fft在内的五种快速算法，结合prc-cw雷达的具体情况，确定了一种适于dsp实现的快速卷积算法。仿真和实测数据证实了数字化方案及快速算法的正确性。
