ABSTRACT:
A microwave locating system is provided for locating known features and distinguishing between different types of features. The locating system includes a plurality of modulated microwave power sources located on known features and radiating modulated microwave signals having modulated frequencies selected in accordance with the known features. A video detection sensor camera is located remote from the sources for sensing microwave signals within a field of view and providing location signals for each of the sources. The camera includes an array of receiver elements which provide narrow bandwidth filtering so as to identify received signals as one of a plurality of selected modulated frequencies. The locating system further provides an image of the location signals which distinguishes between different selected located features.
