%X When a time-frequency approach is applied to analyze the radar emitter signal, the choice of time-frequency atom dictionaries is a key issue and different dictionaries have distinct performances on different signals. In order to make a good choice from various dictionaries, this paper compares five dictionaries with different structural characteristics on five kinds of radar emitter signals with different modulations by the use of quantum-inspired evolutionary algorithms. Experimental results show that the selection of time-frequency atoms is closely related to the characteristics of radar emitter signals.
