摘要
LFMCW在动目标检测上存在一定难度,利用二维FFT处理技术对目标回波信号相位信息进行提取,可有效地抑制固定杂波,对动目标进行检测,该文就LFMCW的差频相位进行了分析和仿真,对二维FFT的具体应用约束和算法的复杂度作了分析。
Moving targets detection by LFMCW has always been a tough issue. Moving targets can be effectively detected and examined and unchangeable clutter can be restrained by extracting information from target echoes using two-dimensional FFT techniques. In this paper, analysis and simulation are carried out over the beat frequency phase that has been deduced. Its further applications are discussed and the algorithm complexity analyzed.
