多载频雷达通信综合化波形设计

Design of waveform for integration of multi-carrier radar and communication

为了减小作战平台体积和相互电磁干扰,雷达通信一体化设计成为一种有效选择.针对通信中已有成熟应用的正交多载频波形,分析了相同编码(IS)多载频相位编码(MCPC)和子载波编码循环移位MCPC作为雷达波形的模糊函数性能.在此基础上,提出用随机通信数据控制MCPC信号子载波相位编码移位位数的综合化波形设计方式,解决了随机性通信信号和确定性雷达信号的不兼容问题.对综合化波形模糊函数和通信效率的分析仿真表明,其雷达探测性能不劣于相同编码MCPC,且具有较高的通信传输效率.

Integration of radar and communication has been an effective choice for reducing the volume of operational platform and mutual EM interference. Aimed at orthogonal multi-carrier waveform commonly used in the communication system, this paper analyzes the performance on the radar waveform＇s fuzzy function that is composed of the identical sequence（IS） multi-carrier phase coded（MCPC） and sub-carrier coding cyclic shifted MCPC, based on which, the design mode for integration waveforms by using the random communication data to control the shifted digits of sub-carrier phase coding of MCPC signals is presented, and the incompatibility problem of random communication signals and deterministic radar signals is solved. By analytic simulation of the fuzzy function of integrated waveforms and communication efficiency, it is shown that its radar detection performance is not worse than that of the identical coding MCPC and of higher communication transmission efficiency.
