Realization of Pseudo-Random Agile Phase-Coded Pulse Compression

The agile phase-coded pulse compression is a new technique in radar signal processing domain. This paper is devoted to the theoretical and experimental investigations of main problems in realization of this technique. A method for constructing sub-optimal code sets is proposed to improve the pulse compression performance by combining phase agility and video integration after pulse compression. The compositions, working processes and performance analyses of the agile code generator, digital correlator and digital integrator are also given. It concluded with computer simulations and hardware real-time experiments been completed.
