Abstract :
This paper proposes a time-frequency analysis algorithm based on spectrum in order to effectively detect overlapped JTIDS signals at the same time. Firstly, the characteristic of JTIDS signal is analysed. Secondly, the signal model is established. Then, hopping cycle and hopping frequency of the signal are effectively estimated by algorithm analysis and simulation, So as to achieve the purpose of detecting multiple JTIDS signal.
