Patent ID: 8026841

Claim:
A method of enhancing range and azimuth resolution in a two-dimensional (2D) image generated by a frequency modulated continuous-wave (FMCW) radar for providing enhanced situational awareness in autonomous approach and landing guidance (AALG) system, comprising the steps of forming and displaying a two-dimensional (2D) model of landing conditions from received range and azimuth real beam radar (RBR) signals by rendering one or more target locations and amplitudes in both range and azimuth; selecting a region of interest from said displayed 2D model to enhance said one or more target locations and amplitudes in said selected region of interest; applying both range and azimuth resolution enhancement to enhanced the rendered one or more target locations and amplitudes in both range and azimuth; and combining the enhanced one or more target locations and amplitudes in range and azimuth to render an enhanced 2D image.
