    • A method of protecting a predetermined area, comprises the steps of: a) providing a base station positioned essentially at the center of the area to be protected, the said base station being provided with scanning laser beam generating and receiving means, image and signal processing units, memory means, voice receiving and transmitting means and image viewing means; b) causing a laser beam generated by the base station to be reflected from the surveyed area into the receiving means of the base station; c) processing the received reflected light to generate an image of the surveyed area; d) storing one or more scanned images in memory means, to be used as reference images; e) at any given time, comparing a real-time scanned image with one or more stored reference image(s), to determine changes which have occurred on the image, which exceed predetermined threshold values, and alerting the operator of the base station of any such changes; f) providing one or more moving station(s) comprising emitting/receiving laser generating means and signal processing means, and causing the said moving station to generate an emitted signal which identifies it; and g) providing recognition means within the signal processing means of the base station, to recognize the signal generated by the moving station as a friendly signal, and to alert the operator of the base station whether a change in the image of the scanned area belongs to a friendly or to an unfriendly force.
    • 一种保护预定区域的方法,包括以下步骤:a)提供基本上位于要保护区域中心的基站,所述基站配备有扫描激光束产生和接收装置,图像和信号处理 单元,存储装置,话音接收和发送装置以及图像观看装置; b)使由基站产生的激光束从被测区域反射到基站的接收装置; c)处理所接收的反射光以产生勘测区域的图像; d)将一个或多个扫描图像存储在存储器装置中,以用作参考图像; e)在任何给定时间,将实时扫描图像与一个或多个存储的参考图像进行比较,以确定在图像上发生的超过预定阈值的变化,并且提醒基站的操作员 任何这样的变化; f)提供一个或多个移动台,该移动台包括发射/接收激光发生装置和信号处理装置,并且使所述移动台产生识别它的发射信号; 和g)在基站的信号处理装置内提供识别装置,将移动台产生的信号识别为友好信号,并且提醒基站的操作者所扫描区域的图像的改变是否属于 友好的或不友好的力量。
