This invention discloses a radiation source signal classification method based on pulse-level multi-source separation, mainly addressing the problem of poor radiation source signal classification performance in complex electromagnetic environments using existing technologies. The implementation steps are as follows: 1) Receiving broadband intermediate frequency or baseband signals and performing pulse detection; 2) Estimating the direction of arrival and constructing pulse descriptors for the detected pulses based on a multi-element antenna structure; 3) Modeling a pulse-level multi-dimensional feature space and performing density peak clustering based on temporal consistency constraints within this space; 4) Adaptively estimating the number of radiation sources and reconstructing the pulse sequence, performing multi-physical domain feature extraction; 5) Fusing the multi-physical domain features to complete the classification and identification of radiation source signals. This invention can effectively distinguish pulses from different radiation sources in complex electromagnetic environments, while effectively reducing the system's storage and computing resource consumption while ensuring high recognition performance.

The utility model provides an ultrasonic coupling agent spraying device suitable for special equipment. The utility model provides an ultrasonic coupling agent spraying device. The ultrasonic coupling agent spraying device comprises a box provided with a holding part, a nozzle assembly, a liquid suction pipe and a limiting switch. A containing groove is formed in the top of the box body, and the nozzle assembly is arranged in the containing groove and can be switched between the vertical direction and the horizontal direction. A limiting switch is arranged on the containing groove and used for limiting movement of the nozzle assembly. The top of the liquid suction pipe is communicated with the nozzle assembly, and the rest part of the liquid suction pipe is inserted into the box body; when the ultrasonic coupling agent spraying device is used, the ultrasonic coupling agent spraying device can be fixed to the hand through the holding part, the limiting switch is controlled through the thumb, so that the nozzle assembly is switched from the horizontal state to the vertical state, then the thumb continues to be operated to control the nozzle assembly, and an ultrasonic coupling agent in the box body flows out of the nozzle assembly; and after the ultrasonic coupling agent is sprayed, the limiting switch is controlled by the thumb again, so that the nozzle assembly is recovered from the vertical state to the horizontal state.
