Problems solved by technology

[0011] In the current popular cognitive radar research field, in the article "Dynamic Design and Analysis of Continuous Chaotic FM Signal" (see Acta Physica 2010, written by Jiang Fei, Liu Zhong, Hu Wen, and Bao Bocheng) published by the inventor, It has been proposed that the frequency spectrum of the output signal can be controlled by designing the frequency modulation signal; however, the phase information of the output signal cannot be obtained from the frequency modulation signal, and the output signal generated by this method also faces the delay problem of broadband signals, which needs to be improved

Abstract

The invention discloses a chaos radar signal source, which comprises a frequency modulation module, a timer, a transducer and a register, wherein frequency modulation signals generated by the frequency modulation module are output on the one hand, and are sent into the transducer after timing sampling by the timer on the other hand; the sampled signals are sent into the register after being subjected to polynomial transform; and an output end of the register is connected with an input end of the frequency modulation module. A chaotic signal generated by the chaos radar signal source has the characteristics of wide frequency band, low peak-to-average power ratio, high pulse compression performance and the like; the delay reconstruction of transmitted signals can be finished in a mode of synchronizing two systems; and the chaos radar signal source has a wide application prospect in the field of radar application. The invention also discloses a method for generating chaos radar signals and a chaos radar signal synchronization system.

Description

technical field [0001] The invention belongs to the application field of communication and radar, in particular to a signal source structure capable of generating chaotic signals. Background technique [0002] Due to the randomness of the chaotic signal and the extreme sensitivity of the chaotic system to the initial value, the chaotic signal has strong confidentiality, it is difficult to be deciphered and copied, and the recognition rate is extremely low, making its application research in communication and radar more and more important. more and more. The application of chaos to radar is an important aspect of the application of chaos in the field of information engineering. Although the research on the application of chaos to radar is later than its application in communication, it develops very quickly. [0003] Chaotic signal radar is usually attributed to random (noise) signal radar system. Random signal radar has a thumbtack-type ambiguity function, which has very hi...
