Abstract

This paper presents a new detection method for unknown frequency hopping (FH) signal, this indirect method is base on multiple image features. We first process the time-frequency spectrum of the received signal, extract image features after image segmentation and filtering operations, then establish FH signal verification and joint parameters estimation (FHSV-JPE) mathematical model to describe the detection problem, we propose an optimal solution of the model, and analyze the performance of the algorithm at last. Simulations are carried out to demonstrate the efficiency of the proposed algorithm.
