Combined radar and communications system using common signal waveform

摘要

A system having a set of common hardware and common signal processing together with a common waveform family that can be used to achieve both efficient radar and efficient communications functions. The system includes a common radar/communications transmitter having a transmission antenna and a combined radar and communications receiver having a common reception antenna. The common radar/communications transmitter is configured to transmit combined radar/communications waveform-modulated signals comprising symbols, each symbol consisting of an up chirp and a down chirp. The combined radar and communications receiver includes a baseband radar signal processing module configured to estimate range and range rate of a radar object from the received symbols and a baseband communications signal processing module configured to detect slopes and initial phases of the up and down chirps of each received symbol.
