This study proposes a sparse linear array synthetic aperture radar (LASAR) on a spaceborne dual platform. The transmitting elements are placed at the LASAR tips that form a satellite's dual platform, and the receiving elements are placed on the large deformation composite pine which is between the satellite's dual platform. Based on the principle of phase centre of approximation and multiple input multiple output, LASAR with the sparse array could obtain a high‐resolution imaging in the cross‐along direction, which is crucial to a three‐dimensional SAR system. Furthermore, the LASAR system has different modes, such as interferometry and ground moving target indication.
