Patent ID: 7327303

Claim:
A hybrid radar receiver for receiving an input signal that includes a radar signal from at least one signal emitter, said receiver comprising: a plurality of antenna elements arranged as an array to receive the input signal, with each antenna element configured to output an analog signal on a respective data channel; a plurality of analog-to-digital (A/D) converters, each converter activatable to receive an analog signal on a respective data channel and convert the analog signal to a digital signal; a dedicated hardware circuit for operating on an analog signal from one of the antenna elements to extract at least one pulse parameter from the analog signal, said hardware circuit configured to compare the extracted parameter to a parameter threshold and use a comparison result to selectively activate said plurality of A/D converters and produce a digital signal on each channel; and a software equipped processor operably connected to receive the digital signal on each channel, said processor configured to use said digital signals in a signal emitter identification algorithm.
