Claim Text:
1. A method for locating at least one signal wave (SW) emitter of unknown modulation and transmitting from an unknown location using a single moving signal collection platform, comprising: collecting a raw data representation of SW signal emissions within a SW emissions environment only at the single moving collection platform, the raw data representation of SW signal emissions including SW emissions of unknown modulation from the SW emitter transmitting from an unknown location, and the raw data representation including data samples having magnitudes that are characteristic of received signal energy of the SW emitter; estimating the signal energy transmitted within the SW emissions environment from a two or three dimensional grid of locations using the raw data representation collected only at the single moving signal collection platform; and determining the location of the SW emitter on the two dimensional or three dimensional grid from an estimated signal energy distribution across the two or three dimensional grid without knowledge of either the modulation or transmitted location of the SW emissions from the SW emitter and without determining any intermediate geolocation observable measurement.
