摘　　要：为使一般伪码调制激光探测系统的升级和改进更简单、方便和廉价,提出把软件无线电技术应用于该系统。从软件无线电技术的基本原理入手阐述了系统的基本体系、硬件平台和软件系统实现。并设计了系统框图和DSP的硬件电路,编制了伪码产生的程序框图、信号处理软件流程图。实验研究表明:把软件无线电技术应用于伪码调制激光探测系统,为整个系统的模块化、小型化、智能化提供了新的有效途径。Software radio technique is applied to laser target detection system with the pseudorandom code modulation. Based on the theory of software radio, the basic framework of the system, hardware platform, and the implementation of the software system are detailed. Also, the block diagram of the system, DSP circuit, block diagram of the pseudorandom code generator, and soft flow diagram of signal processing are designed. It is shown that the application of software radio technique provides a novel method to realize the modularization, miniaturization and intelligence of the system, and the upgrade and improvement of the system will become simpler, more convenient, and cheaper.
