摘要
A radar system, apparatus, architecture, and method are provided for generating a transmit reference or chirp signal that is applied to a waveform generator having a frequency offset generator and a plurality of single channel modulation mixers configured to generate a plurality of transmit signals having different frequency offsets from the transmit reference signal for encoding and transmission as N radio frequency encoded transmit signals which are reflected from a target and received at a receive antenna as a target return signal that is down-converted to an intermediate frequency signal and converted by a highspeed analog-to-digital converter to a digital signal that is processed by a radar control processing unit which performs fast time processing steps to generate a range spectrum comprising N segments which correspond, respectively, to the N radio frequency encoded transmit signals transmitted over the N transmit antennas.
