波動的最簡單形式是橫向簡諧振動和勻速直線運動的組合。Firstly, according to the characteristic that the doppler frequency shift signal can be approximated as a single sinusoid signal, the extended sinusoid signal retrieval ( pisarenko and esprit ) methods are presented and signal state and measurement formulations are developed, so the kalman filter recursive method is got. the brief introduction of low velocity moving target doppler frequency shift signal wigner - ville transformation and wavelet transformation expression are presented in this paper. secondly, because the clutter is gaussian distribution, cumement and high - order spectrum based methods are presented and the simulation results prove their good performance to suppress gaussian clutter in low velocity moving target doppler frequency shift signal processing
一個方面是根據低速目標的多普勒信號可簡化為單一正弦波形式這一特點,得到了擴展的高斯色噪聲背景下的諧波恢復演算法,即高斯色噪聲中的pisarenko諧波恢復法和旋轉因子不變法( esprit ) ;並推導了信號的狀態方程和觀測方程,進而得到基於卡爾曼濾波的遞推演算法對信號進行提取;本文還簡單的介紹了低速運動目標的多普勒頻移信號的wigner - ville變換與小波變換;另一個方面是針對雜波服從高斯分佈這一特點,提出了對接收信號求累積量和高階譜來對高斯雜波進行抑制。
