摘要： Radar signals are generated to have signal characteristics that define multiple sub-pulses in each of a plurality of pulse repetition intervals (PRIs) of a single radar dwell. Electromagnetic radiation is emitted according to the radar signals and the emitted electromagnetic radiation is sensed as radar return signals over a receive interval in each PRI. Coherent integration is performed on a set of the radar return signals and non-coherent integration is performed on another set of the radar return signals.

摘要： A signal processing system including a plurality of receivers configured to receive a return signal from a transmitted radio frequency (RF) waveform. A mode control processor is configured to selectively and independently alter at least one characteristic of a signal down conversion process performed by each receiver. A digital signal processor is configured to integrate the outputs of the plurality of receivers.
