1. A radar system, comprising:

  • a. a waveform generator configured to generate a first signal and a second signal, said first signal having a different shape from said second signal;

    b. amplifiers configured to amplify said first and second signals;

    c. an antenna configured to simultaneously propagate said amplified first signal in a first plane and said amplified second signal in a second plane angularly rotated from said first plane;

    d. a receiver configured to receive a first reflected signal having the shape of said first signal and a second reflected signal having a shape of said second amplified signal;

    e. a stable local oscillator configured to generate a stable oscillating signal at a frequency equal to the difference between said propagated frequency and said intermediate frequency; and

    f. wherein said waveform generator generates said first and second signals at an intermediate frequency less than the frequency of said propagated first and second signals.
