Abstract

For a narrow-beam radar working in a down-looking view, the antenna pattern modulates the ground clutter apparently in the delay/range dimension, causing amplitude/intensity distortion of radar echoes and performance loss of target detection. This paper proposes a range-dimensional clutter distortion correction method based on clutter pre-screening and beam pattern demodulation. This method realizes the correction of clutter distortion, to improve the target detection performance of Narrow-beam radar. The effectiveness of the method is verified through simulations and experimental measurements. The proposed method demonstrates practical significance in improving the detection probability of radar targets under clutter distortion in narrow-beam broadband radar systems.
