This paper presents that software radio technique is applied to laser target detection system with the pseudo-random 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 pseudo-random code generator, and soft flow diagram of signal processing are designed. Experimental results have
shown that the application of software radio technique provides a novel method to realize the modularization,
miniaturization and intelligence of the laser target detection system, and the upgrade and improvement of the system will
become simpler, more convenient, and cheaper.
