Research And Implementation Of Channel Equalization Technique In Adaptive Side-lobe Cancellation

In this paper, the adaptive side-lobe cancellation technique and the adaptive channel equalization technique are mainly studied. The adaptive side-lobe cancellation technique is to restrain the active jamming from side-lobe of radar antenna with digital signal processing technique. And the adaptive channel equalization technique is an effective method that can solve the problem of the channel mismatch in the adaptive side-lobe cancellation system.Firstly, the principle of adaptive side-lobe cancellation is analyzed theoretically, and the mathematics model of adaptive side-lobe cancellation is built and simulated. The problem that channel mismatch affects improvement factor is mainly discussed. Secondly, the adaptive channel equalization technique is introduced and the realization of the adaptive channel equalization algorithm is studied. Then several factors that affect the performance of adaptive channel equalization are analyzed and simulated. The results of the simulation play a most important role in selecting parameters of adaptive channel equalization system. Finally, the realization and application of the adaptive side-lobe cancellation technique and adaptive channel equalization technique in a project are introduced. Moreover, the solutions of some matters that we need to pay attention to in designing and debugging software and hardware system are also given out.
