1. A method for dynamically analyzing radar pulses at a receiver, comprising:
- comparing received signals to each of a plurality of stored matched filters;
providing a digital signal to an amplitude detector in response to a determination that the received signal does not match one of the plurality of stored matched filters;
identifying at least one digital waveform representing an emitter pulse associated with an emitter at the amplitude detector; and
generating a matched filter associated with the emitter, comprising at least one characteristic of the identified digital waveform, when the received signal does not match one of the plurality of stored matched filters.
