通过matlab仿真分析了LFM信号的数字下变频步骤，包含NCO CIC FIR数字滤波器等模块(The digital down conversion step of the LFM signal is analyzed by matlab simulation, including the NCO CIC FIR digital filter module.)

本文利用软件相移技术得到相互正交的参考正弦波信号；通过互相关算法，完成了软正交矢量型LIA相关器的具体实现；利用该方法实现了对微弱信号幅值和相位的检测，有效地抑制干扰，减少了硬件电路成本。通过Matlab仿真，验证了该算法具有一定的优越性。(In this paper, the software technology is orthogonal to the phase shift of the reference sine wave signal through cross-correlation algorithm to complete the implementation of soft orthogonal vector LIA correlator achieved using this method for detecting a weak signal amplitude and phase, effectively suppress the interference and reduce the cost of the hardware circuit. By Matlab simulation show that the algorithm has certain advantages.)

在虚拟仿真环境下进行了几种不同规格零件的抓取试验。在ADAMS中进行仿真试验设置，创建传感器及仿真脚本命令，对两种规格零件进行了抓取试验分析，进一步验证结构设计的正确性及合理性。(the capture of several parts with different specification test was carried out in a virtual simulation environment. To further verify the correctness and the reasonable of the structural design, in ADAMS simulation test, the crawled test and analysis was done for two specifications of parts with the creating of command script and sensor.)
