Abstract:
Systems and methods for efficiently updating text or symbol annunciations outputted by an avionics system on legacy displays. Instead of using a set sweeping pattern to update the display, a smart updating concept is used. The smart updating concept senses when the pilot is adjusting the selected altitude control (or other user interface device that will alter displayed annunciations), then gives priority to updating the radial lines on the display that contain the annunciation field. Once the annunciation field has been updated, the display returns to normal operation.

Abstract:
Signal compensation systems and methods compensate an estimated range profile from a plurality of detected signal returns from a true range profile, wherein the signal returns correspond to an emitted stepped frequency pulse-train. An exemplary embodiment utilizes knowledge of the radar system design to identify locations, predict power levels, and suppress the contributions of stepped-frequency range sidelobes (ambiguous peaks) in the estimated range profile, resulting in a cleaner and more accurate radar display.
Abstract:
Marine radar systems and methods for producing low power, high resolution range profile estimates. Non-linear Frequency Modulation (NLFM) pulse compression pulses are frequency stepped to form a low power, wide-bandwidth waveform. Periodically, calibration filters are determined and applied to return signals for correcting non-ideal effects in the radar transmitter and receiver.
