In the direct implementation, the formulation of the time-scaling and time-varying signal takes much computational load and its formulation accuracy affects the AAF performance. By exploiting the generating dynamics of the wideband signal, it is found that the time-delay and time-scaling wideband signal can be generated by a corresponding dynamical system with synchronization techniques. With this observation, the AAF can be calculated by following the conventional correlation method. Numerical simulation shows that the proposed method has little computational load and is suitable for non-analytical signals. %K Signal processing %K Acceleration %K Wideband signal %K Ambiguous function %K Chaos signal %K Time-scaling varying
