Abstract

The invention provides a radar communication integrated signal generation method and device. The method includes the following steps: performing three-stage design on a communication symbol sequence to be processed, and performing continuous phase modulation (CPM) on the acquired three-stage communication symbol sequence to generate a CPM signal, and loading the CPM signal to a chirp signal to generate a radar communication integrated signal. Thereby, the three-stage design of the radar communication integrated signal can be realized, and thus the radar communication integrated signal can be limited to a bandwidth range of the chirp signal, the out-of-band attenuation and out-of-band interference of a power amplifier and the noise effects can be avoided, the radar communication integrationrequirements can be met, the original working distance and detection tracking performance of radars can be maintained, and the requirements of high-speed data transmission can also be achieved.

Description

technical field [0001] The invention relates to the technical field of radar and communication, in particular to a chirp signal-based radar communication integrated signal generation method and device. Background technique [0002] Radar and communication systems play key roles in modern information networks. In terms of military applications, with the gradual formation of the "land, sea, air and space integration" battlefield information network, all weapon platforms are required to work together and have functions such as battlefield reconnaissance, monitoring, identification, communication, and information fusion processing. In terms of civil use, with the development of intelligent transportation systems, vehicles need to simultaneously complete the detection of the surrounding environment and realize high-speed data transmission through dynamic networking. For a long time, the independent research and development and equipment of radar and communication systems have ca...
