A Special Operation Mode of BoomSAR in Application to Foliage Penetration Imaging

BoomSAR system is a SAR device embarked in the basket of a boom lift, which provides a cheap and flexible platform to evaluate the performance of radar system and signal processing algorithm, especially for foliage penetration imaging. The common BoomSAR system moves along a straight line to produce the synthetic aperture effect. This paper introduces a special operation mode of BoomSAR, where the rotation of boomlift arm is adopted to form a curving synthetic aperture trajectory. The experimental results show the feasibility and effectiveness of this special operation mode in application to foliage penetration imaging and the theoretical resolution performance is achieved
