Abstract


The radar signals modern radar technology is a key technology for a long period of time . Long accumulation of the radar signal can greatly increase the power of the radar , to extend the distance of the radar . This paper first introduces the radar echo signal processing theory , analysis and simulation of digital down conversion , pulse compression , moving target detection , and then a long period of time signal processing method , final analysis coherent segment in a segment between non- coherent accumulation algorithm . It all echo signal segments within the accumulation time , the period of the echo signal of each of pulse to pulse coherent accumulation , and then be considered in the inter-segment distance compensation , between the segments of the non - coherent accumulation , to give the final accumulated result . The analysis of the data of the measured data results show that this method can be effective long accumulation of the target signal , to improve the SNR of a target signal .
