摘要
Abstract
The paper puts forward a method for spike elimination. The algorithm makes use of spike's singular characteristics, and introduces pulse cancellation, CFAR, and thresholds crossing method for spike's location both in range domain and in pulse domain. Spikes are substituted by interpolated value of adjacent signal data. Spikes are removed, while signals keep integrity. Only two pulses delay is introduced during processing. The method's simple procedure makes it easy for practical implementation. The algorithm, based on FPGA chips, has been applied to a radar with satisfying result.关键词
