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.
