摘　　要：针对长期演进计划(Long Term Evolution,LTE)移动通信环境,提出一种实时雷达信号检测方法,用于对雷达主用户的快速检测分析.检测方法基于数字信道化技术,算法实时性好,能够保留被检测信号的幅度、相位等全部信息,并且以信噪比为参数说明了算法的优越性.实验结果表明:本算法较常规频谱统计方法有更高的雷达信号检测信噪比,可集成于硬件芯片中,有良好的实用性.A real time detection method of radar （LTE） mobile communication environment is propos to radar gy, this signal in ed. The a primary user detection and analysis. Based on method Importations, gorith dicate pared be int can be such as regarded as a real-time process digital , and is long term evolution lgorithm is applicable channelized technolo able to retain almost amplitude, phase, etc. The excellence of the new al m is proved based on the signal-to-noise ratio analysis. Experiment results in the good performance of signal-to-noise ratio in radar signal detection, com with those of the classical spectrum statistics algorithms. This algorithm can egrated in the hardware chip, and has better practicability.
