• Existing techniques for cat-eye effect target identification are often computationally intensive.

Purpose of the Study:

• To propose and validate a novel cat-eye effect target recognition method utilizing compressive sensing (CS).
• To develop a Sample Processing before Reconstruction based on Compressed Sensing (SPCS) technique for efficient target extraction.
• To reduce data storage and processing complexity in target identification.

Main Methods:

• Linear projections of image sequences are employed to filter dynamic background noise.
• A novel imaging mechanism for acquiring both active and passive image sequences is presented.
• The SPCS method processes measurement vectors instead of raw image data.

Main Results:

• The SPCS method successfully extracts cat-eye effect targets from image sequences.
• Experimental results demonstrate the feasibility and efficiency of the SPCS method.
• The proposed SPCS method outperforms the shape-frequency dual criteria method in recognition accuracy and efficiency.
