摘要:
雷达侦察系统对于配套实验用雷达信号发射机往往需要可以同时发射多种参数、软件可配置的雷达信号。针对实际需求,提出了一种基于软件无线电(software defined radio, SDR)可重构多通道雷达发射机系统,该系统以SDR平台为构架,通过现场可编程门阵列(field-programmable gate array, FPGA)实现多通道数字信道化发射机结构模型。在建立实信号信道化发射机基本数学模型的基础上,推导并得到了一种具有计算高效、结构简单的多通道雷达发射机模型。在基于SCA软件协议规范下,构建了SDR可重构多通道的雷达发射机模型,给出了硬件软件实现的基本框架和步骤。对提出的多通道雷达发射机高效结构模型进行了MATLAB仿真,验证了多通道雷达发射机高效结构模型的正确性。该结构模型已经在实际系统中得以应用,在工程应用方面具有一定的实用价值。
Abstract:
Radar reconnaissance system requests that the supporting experimental radar transmitter can send radar signals which can simultaneously launch a variety of parameters and the software can be configured. Aiming at the actual demand, this paper proposed an SDR reconfigurable multi-channel radar transmitter system, which uses the SDR platform as a framework to realize the multi-channel digital channelized transmitter structure model by FPGA. Based on the basic mathematical model of the channelized transmitter for the input of real signal, the paper deduced a poly-phase filtering channelized radar transmitter model with high computational efficiency and simple structure. An SDR reconfigurable multi-channel radar transmitter model was built on basis of SCA architecture, the frameworks and steps of the hardware and software were given. A MATLAB simulation was carried out for the proposed multi-channel radar transmitter system model for verifying its correctness. The structure model has been applied in the practical system and has a certain practical value in engineering application.
