Based on the temporal-spatial stochastic radiation field, microwave staring correlated imaging (MSCI) can achieve high resolution reconstruction of the target. In MSCI, the traditional processing method has a bad real-time performance, which need to wait for all the echo signals and require matrix inversions. In this paper, we introduce the sequential least squares (SLS) method to improve the real-time...
Microwave staring correlated imaging (MSCI) can achieve super-resolution in real aperture staring radar imagery by employing temporal-spatial stochastic radiation field. To achieve better imaging performance, sparse reconstruction is commonly used based on the assumption that the scatters are positioned at the pre-discretized grids. However, off-grid problem degrades the performance of MSCI significantly...
According to target sparsity in observation scene, a novel scheme of microwave staring correlated imaging based on compressed sensing (MSCI-CS) is proposed with its established imaging model. As its imaging base and key element, the formation and specific meaning and characteristics of sensing matrix of temporal-spatial stochastic radiation fields (SM-TSSRF) are analyzed, while a new average cross-correlation...
