ABSTRACT:
Receiver dynamic range is improved while maintaining system processing fidelity by placing a processor control attenuator in front of the synchronous detector or other circuitry and A/D converter circuits. This is followed by a digital circuit which reinserts the attenuation that was taken out previously to maintain signal processing fidelity. The control for the attenuator function is from the processor and is determined by looking at the prior pulse repetition intervals (PRIs) of the radar system data and determining from that data what attenuator value to use for the next PRI. This is done for each range bin to be processed.
