Abstract:

An infrared spatial cone-shaped target recognition method based on improved multiple kernel extreme learning machine (MKELM) is proposed in order to solve the problems that infrared radiation intensity sequence is the only data available at long-range detection, the sample size is limited and the signal-to-noise ratio (SNR) is usually low which lead to the difficulty of target recognition. Firstly, variational mode decomposition (VMD) and reconstruction are performed on infrared radiation intensity sequence. Then, time-domain features are extracted based on reconstructed sequences. Finally, whale optimization algorithm (WOA) is used to find the optimal combination of parameters for MKELM, and target recognition experiment is carried out on the simulated spatial cone-shaped target infrared radiation intensity sequence dataset by using improved MKELM. The experimental results verify the effectiveness, recognition accuracy and robustness of the proposed method.

Key words: infrared radiation intensity sequence, spatial target recognition, variational mode decomposition (VMD), whale optimization algorithm (WOA), multiple kernel extreme learning machine (MKELM)
