Abstract :
The article gives a general form of chaos-based FM radar signal, and uses ergodic criterion of chaos sequence - Lyaponov exponent as a criterion, under which the chaos-based FM radar signal having the desired thumbtack ambiguity surface, if the constraint is violated, its ambiguity surface would be away from the expectancy. The conclusion is ensured by several simulation results.
