Abstract
A passive system and method for enabling the display of an image of the location of emitters of electromagnetic radiation that is effective in the lower portion of the HF band. The system essentially includes an array of antennas for receiving electromagnetic radiation from emitters, and for providing a received signal from each emitter in response to the received radiation; a receiver system coupled to each antenna of the array for measuring the phase and intensity of each received signal, and for providing separate coherent phase signals and amplitude signals that respectively indicate the measured phase and intensity; and a signal processor coupled to the receiver system for processing the coherent phase signals and amplitude signals to provide an image signal for generating an image of the emitters. A display device, such as a cathode ray tube or a graph plotter, is coupled to the signal processor for displaying the image of the location of the emitters in response to the image signal.
