Tomographic synthetic aperture radar (TomoSAR) obtains elevation resolution by adding multiple baselines successively in the direction perpendicular to the line of sight, thereby realizing three-dimensional (3D) reconstruction of complex scenes and s

In this letter, we examine a new measure for high resolution and wide swath (HRWS) synthetic aperture radar (SAR) imaging based on an elevated frequency diversity array (EFDA). By highly integrating digital beamforming (DBF) and frequency diversity a

The range ambiguity poses a challenge in radar systems. To solve this problem, the element-pulse coding (EPC) scheme is performed in multiple-input multiple-output (MIMO) radar. In this paper, the signal-to-ambiguous-plus-noise ratio (SANR) is introd

Using ultra-wideband (UWB) impulse radar for detecting and tracking fast-moving small targets over the ocean surface has been considered before with limited applications. The challenges of deploying such radar sensors on small, unmanned marine platfo

In spaceborne synthetic aperture radar (SAR), it is a challenging problem to realize high resolution and wide swath imaging (HRWS) due to the conflict between Doppler and range ambiguities. To mitigate this conflict, a range ambiguity resolution appr

Due to the conflict between Doppler ambiguity and distance ambiguity, tranditional single channel synthetic aperture radar (SAR) system fails to achieve azimuth high-resolution and wide-swath imaging at the same time. To mitigate this conflict,a rang

With the advent of low-cost, highly capable unmanned aerial platforms, the need arises for equivalently low-cost, highly capable sensors. Traditional high-power pulsed RF systems can be costly and complicated, making them unsuitable for these applica
