At the same time, with the rise of the demand for target information refinement the bandwidth and data volume of radar are also increasing, which limits further application of radar equipment to a certain extent. To solve this problem, 1-bit quantization technology has received more and more attention because of its advantage of reducing the amount of data. However, the highly nonlinear process of 1-bit quantization brings about frequency inter-modulation and greatly complicates signal components, bringing new challenges to radar detection. This paper analyzes this problem and theoretically shows the model of quantization noise. Then, it analyzes how the non-linear effect affects the performance of target detection in the radar system. This gives a good theoretical reference for design of radar system based on 1-bit quantization., authors=WU Yuezhou¹, LIU Shiqi^2*, WANG Xingyi¹, LI Bing^3,4, authorsList=WU Yuezhou, LIU Shiqi, WANG Xingyi, LI Bing, authorCompany=1.
