An apparatus for acquiring and displaying a radar image, the apparatus comprising: an antenna configured to receive a reflected radar signal; a processor configured to: convert the received radar signal into a received power function versus an azimuth, and generate a resolution-enhanced map image by being configured to: create a received power azimuth bin array, calculate a window function from an antenna beam response pattern, calculate at least one product function by multiplying the received power azimuth bin array by the window function, characterised in that the processor is further configured to: calculate an estimated azimuth bin offset based on a mean of the at least one product function and a window function mean, calculate an azimuth position of an estimated target location based on the azimuth bin offset and the window function mean, and add a reflected power value corresponding to the integral of the at least one product function to an element of a reconstructed azimuth bin array corresponding to the estimated target location; and a map display configured to display the resolution-enhanced map image. an antenna configured to receive a reflected radar signal; a processor configured to: convert the received radar signal into a received power function versus an azimuth, and generate a resolution-enhanced map image by being configured to: create a received power azimuth bin array, calculate a window function from an antenna beam response pattern, calculate at least one product function by multiplying the received power azimuth bin array by the window function, convert the received radar signal into a received power function versus an azimuth, and generate a resolution-enhanced map image by being configured to: create a received power azimuth bin array, calculate a window function from an antenna beam response pattern, calculate at least one product function by multiplying the received power azimuth bin array by the window function, create a received power azimuth bin array, calculate a window function from an antenna beam response pattern, calculate at least one product function by multiplying the received power azimuth bin array by the window function, calculate an estimated azimuth bin offset based on a mean of the at least one product function and a window function mean, calculate an azimuth position of an estimated target location based on the azimuth bin offset and the window function mean, and add a reflected power value corresponding to the integral of the at least one product function to an element of a reconstructed azimuth bin array corresponding to the estimated target location; and at least one product function and a window function mean, calculate an azimuth position of an estimated target location based on the azimuth bin offset and the window function mean, and add a reflected power value corresponding to the integral of the at least one product function to an element of a reconstructed azimuth bin array corresponding to the estimated target location; and calculate an azimuth position of an estimated target location based on the azimuth bin offset and the window function mean, and add a reflected power value corresponding to the integral of the at least one product function to an element of a reconstructed azimuth bin array corresponding to the estimated target location; and a map display configured to display the resolution-enhanced map image.
