基于基频提取的舰船目标识别系统设计
Design of Warship Target Recognition System Based on Fundamental Frequency Extraction
摘要
Abstract
With the development of minesweeping gear technology, we present a fundamental frequency extraction method of a warship according to the difference between the low-frequency power spectrums of warship and mine-sweeping gear in order to distinguish a warship target from a minesweeping gear. Considering these factors, we use ultra-power devices OPA378, ADS7951 and TMS320VC5509A to design a fundamental frequency extraction system of warship with low power, quickness and real time. This system uses difference frequency algorithm to estimate target base-band. Experiments verify the stability and reliability of the system.关键词
