  • Patent number: 10481245
    Abstract: The concepts, systems and methods described herein are directed towards frequency jump burst-pulse-Doppler (FJB-PD) waveforms and processing to provide wideband, high range resolution (HRR) radar profiling capability in a clutter dense environment. The method includes transmitting a FJB-PD waveform comprising a plurality of frequency steps over a predetermined time period with each frequency step having a plurality of pulses. The method further includes receiving one or more FJB-PD pulse returns corresponding to the FJB-PD waveform and identifying one or more target detections in the one or more FJB-PD pulse returns. A set of range swaths may be extracted for each of the one or more target detections and a wideband spectrum may be generated for each of the sets of range swaths using FJB coherent integration. A clutter suppressed HRR profile may be generated for each of the target detections based on the respective wideband spectrum.

  • Patent number: 9250313
    Abstract: An analog-to-digital converter circuit for a radar apparatus, the analog-to-digital converter circuit including analog-to-digital converters that are electronically reconfigurable to operate in a multi-channel mode with a first bandwidth by clocking the ADCs in phase with one another, or a single-channel mode with a second bandwidth higher than the first bandwidth by clocking the ADCs out of phase with one another and optimizing the intermediate frequency for the respective mode.
