Abstract
An efficient receiver system (80) adapted for use with a pulsed radar system. The receiver system (80) includes a first circuit (82) for receiving a first signal and providing a second signal in response thereto. A second circuit (96) compares the second signal to a predetermined sequence (98) and provides a compare signal in response thereto. A third circuit (104) stores information pertaining to the second signal in response to the compare signal. A fourth circuit (92) generates receiver system instructions based on the stored information. In a specific embodiment, the second signal is a digital signal and the sequence is a digital sequence. The pulsed radar system includes a circuit for receiving and collecting data during a first dwell and for processing the data during a subsequent dwell. An inter-dwell time interval exists between the first dwell and the second dwell. The first, second, third, and/or fourth circuits (82, 96, 104, and/or 92) operate during the inter-dwell period. The information pertaining to the digital signal is information specifying whether an existing frequency channel on which the signal is received by the receiver system (80) is corrupted with electroma…
