Claim One:
1. In an automotive radar system disposed in a vehicle, a radar imaging process comprising: (a) while the vehicle is moving, transmitting, via the automotive radar system, a first plurality of radio frequency signals toward an object; (b) while the vehicle is moving, receiving, via the automotive radar system in the moving vehicle, 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) while the vehicle is moving, transmitting, via the automotive radar system a second plurality of signals; (e) while the vehicle is moving, receiving a second plurality of return signals at the automotive radar system, the second plurality of return signals having a Doppler shift resultant from movement of the vehicle relative an object; (f) converting the second plurality of return signals to a set of signal strength vs. Doppler shift measurements; (g) using a signal strength value, a monopulse angle value 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.
