Chaos radar signal source and chaos radar signal synchronization system

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.
