Problems solved by technology
[0004] In the existing method, when the integrated radar communication system is used to realize the radar detection process and the communication process, only one-way communication and one-way radar detection can be realized. For example, equipment 1 and equipment 2 have a set of antennas respectively, and equipment 1 and equipment 2 One-way communication and one-way radar detection are performed through the antenna, that is, at the same time, the antenna can only be used to transmit signals or receive signals, so that it can only meet the one-way communication and one-way radar communication integrated system. Radar Detection Requirements

Embodiment Construction
[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0066] With the rapid development of wireless communication technology, the spectrum allocated to wireless communication is constantly developing towards high frequency band and large bandwidth. Especially after the opening of the millimeter wave frequency band, the frequency spectrum for wireless communication and the frequency spectrum allocated for perception and perception show an increasingly obvious trend of integration. In addition, with the rapid devel...

The embodiment of the invention provides a radar communication integrated system, a signal processing method and device, and a storage medium. The radar communication integrated system comprises a first device and a second device, wherein both the first device and the second device are provided with a transmitting antenna and a receiving antenna; the transmitting antennas and the receiving antennas are carried on a radar communication integrated device; the communication working mode of the first device and the second device is a simultaneous same-frequency duplex working mode; the first device and the second device use different code channels to transmit signals, and the signals are code division multiple access-orthogonal frequency division multiplexing (CDM-OFDM) signals; the first device and the second device perform bidirectional simultaneous communication by generating a transmitting beam and a receiving beam respectively; the transmitting beam is scattered at the communication receiver to generate an echo signal, and the echo signal is received by a receiving antenna of a communication transmitter to perform radar signal processing. In this way, the duplex interaction requirement for the radar communication integrated system can be met.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a radar communication integrated system, a signal processing method and equipment, and a storage medium. Background technique [0002] With the rapid development of wireless communication technology, the spectrum allocated to wireless communication is constantly developing towards high frequency band and large bandwidth. Especially after the opening of the millimeter wave frequency band, the frequency spectrum for wireless communication and the frequency spectrum allocated for sensing show an increasingly obvious trend of integration. In addition, with the rapid development of digital signal processing technology, analog to digital converters (Analog to Digital Converter, ADC / Digital to Analog Converter, DAC) and digital processor modules of perception systems and wireless communication systems are Moving forward, the system structures of the two are becoming more and mor...
