7.4. The Synthetic Aperture Radar (SAR) ambiguity function can be approximated by

where x is the variable for the range-compressed axis, y is the azimuth-compressed axis, and k and r are related to the SAR range and azimuth resolutions.

(a) Generate the x-axis from -40m to 40m using a sampling interval of 0.1m. Assume k = 1. Plot the magnitude of this range profile.

(b) Generate the y-axis from -40m to 40m using a sampling interval of 0.1m. Assume = 0.00015 and N = 1000. Plot the magnitude of this azimuth profile.

(c) Use the findings in

(a) and

(b) to generate the two-dimensional ambiguity surface plot.
