运动目标模拟器相参性分析，分析了基于数字射频存储器(DRFM)的运动目标模拟器(MTS)相参性。由于DRFM延时的离散性,引起了MTS输出信号相位的改变,破坏了信号的相参性,使MTS输出信号频谱发生变化,不仅使谱线位置移动,而且还产生了附加的寄生谱线。分析结果表明,延时更新率(Fc)决定了谱线间隔,并通过sinc函数决定谱线的幅度,而雷达信号频率与所模拟目标的速度共同决定谱线的移动。 (Moving Target Simulator Coherent Analysis, Moving Target Simulator (MTS)-based digital radio frequency memory (DRFM) coherent. Due to the the DRFM delay discrete MTS output signal of the phase change is caused, the destruction of the phase of the signal parameters, the MTS output signal spectrum changes, not only the spectral line position, but also generates additional parasitic spectral line. The analysis results show that the delay update rate (Fc) determines the spectral interval by sinc function determines the amplitude of the spectrum, while the radar signal frequency and speed together determine the movement of the spectral lines of the simulated target.)

The Kalman filter is a mathematical power tool that is playing an increasingly important role in computer graphics as we include sensing of the real world in our systems. The good news is you don’t have to be a mathematical genius to understand and effectively use Kalman filters. This tutorial is designed to provide developers of graphical systems with a basic understanding of this important mathematical tool.
