Chaos-based security robust radar communication integrated system, control method and medium

Abstract

The invention belongs to the technical field of radar and communication, and discloses a chaos-based security robust radar communication integrated system, a control method and a medium. The system comprises a plaintext electric signal module, a delay keying modulation module, a first nonlinear transformation module, a synchronous channel, a delay module, a second nonlinear transformation module, a plaintext recovery module, a first anti-time chaos module, a radar transmitter module, a radar wireless channel, a radar receiver module, a second anti-time chaos module, and a data processing and control module. Information transmission between a sender and a receiver is carried out through chaos delay keying, remote synchronization of information is achieved by means of the delay characteristic of signals, meanwhile, the secret communication function is achieved by means of the spread spectrum characteristic of chaos keying, and the method can be used for a system for large-scale radar detection and transmission of a large amount of information.

Description

technical field [0001] The invention belongs to the technical field of radar and communication, specifically relates to the technical fields of chaos security communication technology and bistatic noise radar, and in particular relates to a chaos-based safe and robust radar communication integrated system, control method and medium. Background technique [0002] At present, in order to meet the needs of communication, 5G has developed into a new generation of communication system. Communication and radar can share frequency bands, which greatly saves spectrum resources. Under the existing hardware conditions, integrate communication and radar on the same platform, and design a system that can realize information transmission and radar detection at the same time, which is helpful for reducing system size, alleviating the shortage of spectrum resources, and reducing electromagnetic interference between devices It has important research significance. [0003] In the radar comm...
