TECHNIQUE FOR ROBUST CHARACTERIZATION OF WEAK RF EMITTERS AND ACCURATE TIME DIFFERENCE OF ARRIVAL ESTIMATION FOR PASSIVE RANGING OF RF EMITTERS |
摘要 |
A system for locating the position of an emitter emitting a signal having time domain features is described. At least two platforms are used. Both have a receiver for detecting the emitter signal, an FFT channelizer to act as a bandpass filter for extracting the time domain features from the emitter signal, and a thresholder for thresholding the time domain signal. An FFT transform and a correlator using templates further extract frequency domain markers identifying the emitter. The frequency domain markers identifying the emitter are transmitted between platforms using a wireless link increasing the probability of detection of the emitter at all platforms.
