In order to address the problem of detecting and tracking low signal-to-noise-ratio (SNR) targets in bistatic passive coherent location (PCL) system, an improved dynamic programming track-before-detect algorithm is proposed. First, the polar measurements are converted to Cartesian measurements. Second, the Cartesian measurements are clustered with the neural network, and the amplitudes of the valid...
In this letter, we develop an active learning algorithm to optimize the selection of training data for robust linear regression. This algorithm selects training data based on the principle of correlation matching between the training dataset and the overall data pool. Considering the inevitable and potentially heavy human labeling errors, we model the probability of labeling errors based on the item...
The researches of imaging algorithms for synthetic aperture radar (SAR) is focused on the air- and space-borne SAR from the theory of SAR was formed . In this paper, we propose a modified frequency scaling algorithm for missile-borne SAR imaging. According to the characters of missile-borne SAR including high flight speed, non-straight movement with non-constant velocity and big squint angle, which...
