ABSTRACT:
Unique stretch and chirp waveform formats are described which allow significant simplification of radar signal generation and receive processing hardware. The new formats produce a non-zero intermediate frequency (IF) to facilitate in-phase and quadrature (I/Q) processing but allows the use of a homodyne type of receiver architecture. That architecture greatly simplifies the receiver hardware because the first local oscillator (LO) signal is simply a sample of the transmitter drive signal and no second LO is required. The non-zero IF is achieved by control of the timing and start frequency of the first LO waveform for stretch processing and timing of the transmit signal gating for chirp processing.
