【摘要】 本文介绍了一种新型的智能地面警卫系统(SIGGS)，从理论和原理上对小型智能地面警卫系统作了系统性的研究。首先简要地阐明了系统的总体结构组成、工作原理和运作过程；然后对系统涉及到的某些关键技术部分作了理论上的探讨。 对于地面传感器子系统，根据国内外无人值守地面传感器的发展情况，提出了地面传感器的选取原则和要求，并优先选用地震动传感器；对于信号传输子系统，提出了采用扩展频谱通信方法来实现传感器与控制中心的通信；对于发射子系统，分析了发射装置的功能和特性要求，并提出了总体结构的设计思路和要求；对于控制子系统，首先列举并比较了多种信号处理的方法为提取特征以识别目标作好了准备工作，而后提出了采用传感器单元阵列网络布设的方法来实现目标的精确定位，并分析建立了打击目标的自动瞄准模型，还对执行机构的控制进行了分析；最后对这种新型地面警卫系统的若干部分作了计算机仿真。 该系统作为地雷武器的替代品，很有实用意义。更多还原

【Abstract】 In this paper, a new ground guard system is put forward. The author has made a systemic study and research theoretically. The whole construction, the working principles and the conduct process of the system are summarized. And some key technologies in this new guard system are analysed.As for the system of ground sensor, in terms of the domestic and overseas developing status in ground sensors, the author puts forward the demands and rules which can be the reference to select the types of ground sensors, and the seismic sensor is the superior one;As for the microseismic signals communicating system, by means of spread spectrum communication the communication between the seismic sensors and the control center can be realized;As for the launching system, the demands in function and characteristic are analyzed and the designing idea and method of the whole construction are introduced;As for the control system, in order to recognise the objects, the author introduces and compares a few DSP methods in which the various features are extracted.And then, to localize the objects accurately, the author puts forward the array techniques for Unattended Ground Sensors(UGS),and the automated aiming model is established, and the control to the performing part is analysed; In the end, some simulation in computer is performed and concluded.So this system is practically useful, as a replacement of mine.更多还原
