Abstract
This letter presents a novel approach for receiving the communication data integrated with radar signals based on chirp sequence (CS). The receiving procedure mainly depends on evaluating a part of the receive signal and correlating it with a reference chirp within a narrow band to reduce the costs compared to the condition when the whole radar bandwidth is also appointed for communication purposes. The transmit signal, in its turn, is an adaption of long-range (LoRa) communications to support both radar and communication features. A measurement setup including a field-programmable gate array as a proof concept is presented to evaluate the radar functionality. Finally, simulations and measurements in terms of the symbol error ratio (SER) are adopted to ensure the capability of the proposed method of integrating communication data within the radar signals.
