Direct digital synthesis (DDS) architectures are becoming more prevalent as modern digital-to-analog converter (DAC) and programmable logic devices evolve to support higher bandwidths. The DDS architecture provides the benefit of digital control but

Radio tomographic imaging and noise radar are two proven surveillance technologies. The novelty of fusing data from radio tomographic imaging and noise radar is achieved with the derivation of a fusion technique utilising Tikhonov regularisation. Ana

This paper presents an atmospheric optical turbulence mitigation method that uses a sequence of short-exposure frames. An iterative block matching registration method is proposed for image dewarping. The dewarped frames are combined in a least square

We introduce a new LiDAR polarimeter architecture enabling measurement of a large subset of a target Mueller matrix in a single ~10-ns laser pulse; this may be beneficial for remote sensing from moving platforms in terrestrial and defense application

We present a new active imaging architecture that enables rapid spectropolarimetric imaging in a compact system. The transmitter laser produces a synchronous cascade of closely spaced wavelengths, each of which is modulated with a unique amplitude pa

This paper investigates anisoplanatic numerical wave simulation in the context of lucky look imaging. We demonstrate that numerical wave propagation can produce root mean square (RMS) wavefront distributions and probability of lucky look (PLL) statis
