Automobile anti-collision radar based on constant index spectrum chaotic signal source

The invention discloses an automobile anti-collision radar based on a constant index spectrum chaotic signal source. The automobile anti-collision radar is characterized in that a constant Lyapunov index spectrum chaotic signal source is adopted for generating chaotic detection signals, and relevant and summing double passages are utilized for detecting the obstacle distance information; and the staggered time cooperated work of the double passages is utilized, the displacement measurement in a certain time interval is realized, and further, the speed can be obtained. The constant index spectrum chaotic signal source has the amplitude modulation control characteristics and the reverse phase control characteristics, the amplitude modulation depth is convenient to modulate and control, and the summing distance detection is favorably realized. The reverse phase control characteristics can replace the reverse synchronous control scheme, and the design difficulty of a synchronous controller and the realization difficulty of a circuit are reduced. The distance detection reliability is enhanced through the control on the double-passage detection through software, the simple speed detection is also realized, the triggered automobile warning signals and the brake action ensure the safety of moving automobiles, and the anti-collision effect is realized. The automobile anti-collision radar belongs to radar communication equipment and can be used for the safety detection of various moving objects.
