According to one embodiment, a method for autofocus based compensation of range data acquired from an object in motion is provided. The method may include: receiving range data; steering at least one receive beam of the range data in a desired direction; transforming the range data into the range domain; determining the width of a main clutter lobe; excluding data that is not part of the main lobe clutter response; transforming the main-lobe clutter response into the range domain; calculating a phase correction term; and applying the phase correction to the original range data.
  • System And Method For Enabling Radar Operation In A Spectrally Congested Environment

    view source
  • US Patent:
    20180348341, Dec 6, 2018
  • Filed:
    Jun 5, 2018
  • Appl. No.:
    16/000452
  • Inventors:
    - Adelphi MD, US
    Marc Allan Ressler - College Park MD, US
    Kenneth I. Ranney - Monrovia MD, US
  • International Classification:
    G01S 7/295
    G01S 13/89
  • Abstract:
    Embodiments of the present invention implement a novel methodology for processing radar image data from a radar system having one or more transmitter and receiver antenna pairs. The novel methodology deliberately operates on spectrally-notched radar data. It uses a specially-adapted version of the CLEAN algorithm to mitigate the effects of frequency-band notching. Following that, it performs a non-linear sidelobe-reduction algorithm to further eliminate artifacts and produce radar imagery of much higher quality. In some cases, it exploits a specific version of the recursive sidelobe minimization (RSM) algorithm which operates in the frequency and aperture (spatial) domain.

  • International Classification:
    G01S 7/02
    H04W 16/14
  • Abstract:
    A method for optimizing bandwidth selection of a radar transmission in a frequency bandwidth in which the frequency bandwidth is divided into a plurality of sub-bands having a plurality of different bandwidths. The energy level is measured for each sub-band and a range resolution is also determined for each sub-band. Thereafter, a sub-band is selected in the frequency range where the signal to interference plus noise ratio plus the range resolution is maximum. Thereafter, a radar transmission is transmitted in the selected sub-band with a bandwidth corresponding to the bandwidth of the selected sub-band.
