A Target Identification Method for the Millimeter Wave Seeker via Correlation Matching and Beam Pointing

Area of Science:

• Radar Systems Engineering
• Signal Processing
• Target Recognition

Background:

• Millimeter wave (MMW) seekers face challenges in target identification against land backgrounds, particularly in complex environments.
• Accurate target detection and identification are critical for seeker performance.

Purpose of the Study:

• To propose an effective method for target identification in challenging land backgrounds for MMW seekers.
• To enhance the accuracy and reliability of target detection using correlation matching and beam pointing.

Main Methods:

• A two-round seeker scanning approach for initial target detection and information storage.
• Utilizing high-resolution range profiles (HRRP) for point or body feature judgment.
• Constructing an error distribution zone relative to the beam pointing origin for target localization.

Main Results:

• The proposed method successfully identifies targets by locating them within the closest error distribution zone to the beam pointing center.
• Validation using mooring test-fly and real flight data confirmed the method's effectiveness.

Conclusions:

• The combined correlation matching and beam pointing method offers an effective solution for MMW seeker target identification in complex land backgrounds.
• The approach demonstrates robustness and accuracy in real-world flight conditions.
