A Small Smart Ground Security Systems

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.
