任意相位编码信号及其脉压滤波器联合优化设计

Abstract

Abstract:

For the polyphase codes with arbitray phase, an optimal design method combined with pulse compression filters is proposed. Under the constraint of the maximum gain loss, The minimum peak sidelobe suppression correlator for existing phase codes is given by convex optimization, on the basis of which, a novel phase code is presented. Its range sidelobe can be farther decreased by multi-iterative operations. Without increasing the length of pulse compression filters, a nearly optimal peak sidelobe level is achieved by the presented method at the cost of less loss in process gain. The presented algorithm has many advantages, such as flexible design and quick convergence. The validity of the presented method is demonstrated by simulation results.

Key words: waveform design, convex optimization, gain control, correlators
