“…The application to vehicle targets has been limited thus far, with simple 3D renderings being produced of model tanks [15]. Applying this technique to sparse 3D swarm sensing may be complicated by the need to estimate scatterer reflectivity for multiple bistatic angles, although simulated 3D renderings have been formed [16].…”

“…This is due to its electromagnetic wave characteristics and motion imaging mechanism [1]. With the rapid advancement of SAR systems, they have been widely applied to high-speed maneuvering platforms, including airplanes [2][3][4][5], missiles [6][7][8][9], and unmanned aerial vehicles [10][11][12][13] for flight navigation, terminal guidance, and autonomous landing in areas of interest. Among the modes and applications mentioned above, the high-speed SAR system has several distinct features that require special consideration in SAR imaging algorithms.…”

“…When considering the effectiveness of different antenna arrays for radar systems, the maximum directivity of a planar array at boresight is well established [4]. However, as new radar systems paradigms are introduced such as multi-static radar systems for detection and tracking [5,6], or imaging radar [7][8][9], the assumption of coherent beamforming using the full array cannot be relied upon. In addition to these proposals, the introduction of MIMO (multiple input, multiple output) radar, and staring radar [10][11][12][13] which depend upon an antenna array and transceiver with multiple independent transmit and receive channels.…”
