Abstract
A method for estimating the number of emitters of intermittent or periodic pulsed energy waveforms received at a sensor location and the parameters of the intermittent or periodic energy waveforms, including: accumulating over a selected period of time output of the sensor, the output consisting of a set of vectors, each of the 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 the element(s) for each of the waveforms received when at least the parameter of direction is included; dividing the space into a plurality of bins, considering each vector in turn, and apportioning weight of each vector to be accumulated within at least some of the plurality of bins; determining at the end of the selected period of time which of the bins exceed a threshold strength and are, therefore, the emitters; and calculating the at least one element of parameters for each emitter as appropriate for the vector elements selected for the space.
