This paper presents a novel approach for linear sampling method (LSM) to conduct remote sensing for radar applications, such as automotive radar sensors, by incorporating frequency mapping antenna array based on metamaterial leaky wave antennas (MTM-LWAs). Unlike traditional LSM using only one single frequency to illuminate in a certain direction, the proposed approach utilizes a frequency scanning MTM antenna array to perform frequency-space mapping over the targeted three dimensional (3D) background that includes unknown objects, resulting in a significantly increased field-of-view (FOV). The information obtained from the frequency-space scanning scheme is then transferred to the LSM analysis to detect the locations and shapes of the unknown objects. The proposed novel frequency scanning scheme in combination with LSM serves as an efficient 3D remote sensing scheme without the use of any phase shifters.
