摘　　要：随着雷达技术的发展,雷达设备被越来越广泛地应用于各个领域。而随着雷达频带的宽带化和数据的精细化,雷达数据量越来越大,已成为限制雷达发展的瓶颈之一。单比特量化技术的发展和在雷达系统中的引入为解决这一问题提供了有效途径,可显著降低数据量,但也随之带来了新的挑战。本文针对LFM(linear frequency modulation)雷达分析了匹配滤波和去调频2种典型处理方式下单比特量化带来的主要问题。这些问题的分析将为单比特雷达系统设计提供参考。With the development of radar technology,radar equipment is more and more widely used in various fields.However,with the extension of radar frequency band and the refinement of data sampling,the amount of data in radar system is getting larger and larger,which has become one of the bottlenecks restricting the development of radar technology.The development of one-bit quantization technology and its introduction in radar system provide an effective way to solve this problem,which can significantly reduce the data volume,at the same time,it also introduces new challenges.In this paper,the main problems of one-bit quantization in matched filtering and dechirp are analyzed for linear frequency modulation(LFM)radar.The analysis of these problems will provide reference for one-bit radar system design.
