A digital signal processor is designed to channelize an input signal, and includes a channelizer circuit and a plurality of tuning modules. The channelizer circuit is designed to receive an input signal having a first bandwidth and to channelize the input signal into a first set of channels each having a bandwidth smaller than the first bandwidth as a first output signal and to channelize the input signal into a second set of channels having a bandwidth smaller than the first bandwidth as a second output signal. The plurality of tuning modules are designed to receive one or more channels from the first output signal or the second output signal and to further downsample the one or more channels to a user-defined bandwidth at a user-defined center frequency. Each of the plurality of tuning modules include a plurality of FIR filter blocks and a memory having a plurality of FIR filter coefficients.

A system and method for estimating the geographic location of an RF emitter which involves spatially filtering and receiving RF signals through use of a beamforming antenna array having multiple overlapping beams; detecting and measuring the time-of-arrival and amplitude of signals which are received in each beam through use of multiple synchronized receivers; identifying simultaneous detections of the same emitter which have occurred in adjacent beams; projecting the associated beamformed antenna gain patterns onto the underlying terrain for all instances in which there was a simultaneous detection in adjacent beams; weighting and accumulating all projections to form a Maximum Likelihood Surface (MLS); and finally, estimating the location of the emitter through analysis of the resulting MLS.
