Claim One:
1. In an automotive radar system, a radar imaging process comprising: (a) transmitting a first plurality of radio frequency signals toward an object; (b) receiving a first plurality of return signals at the automotive radar system; (c) converting the return signals to a set of signal strength vs. range measurements using a fast Fourier transform (FFT); (d) transmitting a second plurality of signals; (e) receiving a second plurality of return signals at the automotive radar system; (f) converting the second plurality of signals to a set of signal strength vs. Doppler shift measurements stored in range/Doppler bins of the automotive radar system; (g) using a signal strength value and a monopulse angle value stored in range/Doppler bins and a range and angle in radar coordinates, plotting the signal strength returned from the object as an image in x-y coordinates relative to the radar on the host vehicle; (h) knowing the radar mounting location on the host vehicle, plotting the image in host vehicle coordinates; and (i) using host vehicle position and host vehicle heading, plotting the image in world coordinates.
