Abstract:
1. A radar signal processing system, comprising: a digital signal processor comprising first, second, and third inputs and first and second outputs; an IF modulator for generating IF signals from a first output signal of said digital signal processor; a signal generator for providing analog amplitude and phase signals from an output signal of said IF modulator; a first A/D converter for generating in-phase digital signals from said phase signals of said signal generator; said in-phase digital signals being supplied to a first input of said digital signal processor; a π/2 (90°) phase shift component for providing a 90° phase shift quadrature analog signal from said phase signals of said signal generator; a second A/D converter for generating quadrature phase digital signals from an output of said a π/2 (90°) phase shift component; said quadrature phase digital signals being supplied to a second input of said digital signal processor; a RF signal transmitter; an input of said RF signal transmitter being supplied with a signal from a second output of said digital signal processor; an antenna configuration for transmitting and receiving RF signals through a medium of interest; said antenna configuration further comprising: a RF signal receiver for collecting reflected radar signals; an input of said RF signal receiver being coupled to said receiving antenna; and an output of said RF signal receiver being coupled to a third input of said digital signal processor.
