Abstract

This paper addresses the problem of fast computation of the ambiguity function using a new method based on pre-weighted Zoom FFT algorithm, which employs Zoom FFT technique and performs the weighting process previously and thus gets ride of the extra computation. The computational complexity of the presented algorithm is compared with other methods and the simulation results are given. Both the theory and the simulations show that, pre-weighted Zoom FFT method has lower computational complexity, less memory need and negligible error, and can meet the need of real-time processing.
