Methods for estimating the number of emitters and their parameters
First Claim
1. A method for estimating the number of emitters of intermittent or periodic pulsed energy waveforms received at a sensor location and the parameters of said intermittent or periodic energy waveforms, comprising:
- (a) accumulating over a selected period of time output of said sensor, said output consisting of a set of vectors, each of said vectors consisting of at least one element of parameters of direction, frequency, and amplitude, and which element(s) specify(ies) a point in a space defined by said element(s) for each of said waveforms received when at least said parameter of direction is included;
(b) dividing said space into a plurality of bins, considering each said vector in turn, and apportioning weight of said each said vector to be accumulated within at least some of said plurality of bins;
(c) determining at the end of said selected period of time which of said bins exceed a threshold strength and are, therefore, said emitters; and
(d) calculating said at least one element of parameters for each said emitter as appropriate for said vector elements selected for said space.
