  • Patent number: 8704703
    Abstract: Methods and systems for post processing synchronization of bistatic radar data are disclosed. A transmitter is configured to transmit pulses at a first rate controlled by a first local oscillator. A receiver is configured to receive pulses at a second rate controlled by a second oscillator. A processing device is configured to synchronize, with respect to the first rate, in-phase quadrature data received from the receiver using a keystone formatting technique.
    Type: Grant

  • Publication number: 20090128401
    Abstract: A system comprising a moving radar, a processing device, and a phase difference determination device is used to monitor a target. The moving radar has first and second phase centers that transmit and receive signals normal to a direction of movement of the radar. The processing device receives first and second ones of the received signals from the first and second phase centers, respectively, and performs a target motion compensation and target acceleration correction for each of the first and second received signals to produce first and second images. The phase difference determination device determines a phase difference image from a comparison of the first and second images.

  • Publication number: 20090091492
    Abstract: Methods and systems for detecting and mitigating DRFM-based interference in SAR images are provided. Embodiments include methods and systems for detecting and removing DRFM-based interference from SAR images by exploiting multi-channel SAR data. Embodiments provide an Electronic Counter Counter Measure (ECCM) technique that is effective against, among others, SAR DRFM-based repeater jamming, false target images, noise jamming, and vector multiplier jamming for false scene generation. When used, embodiments of the present invention reduce jammer effectiveness to a small range strip (a strip parallel to the range dimension) in the direction of the jammer. In addition, jammer mitigation is performed without losing SAR image data at the affected SAR pixels. Furthermore, embodiments of are compatible with time variable ECCM techniques, including orthogonal waveforms or pulse jitter techniques, for example.
