An algorithm which can detect weak signals on the condition of strong correlated interference is designed in the paper. The algorithm based on conventional beam forming (CBF) can put nulls on given directions. And the weights only relating to interference's direction is given in the paper. Comparing to adaptive methods, the algorithm is robust and the calculation account is smaller. Simulation results...
This paper proposes a novel change detection algorithm for locating target concealed by foliage using multi-pass low-frequency SAR images. Having registered the image pair, an intensity ratio detector is used to detect the potential changes due to disturbance in local mean backscatters with an computed threshold according to a given probability of false alarm. Once a local change is reported, CFAR...
This paper derives an asynchronous track-to-track fusion algorithm that combines tracks provided by different sensors that have different sampling communication delay. In this algorithm, an adaptive approach for track-to-track fusion in a multi-sensors environment is used. The measurements of two sensors tracking the same target are processed by linear Kalman Filters, and the outputs of the local...
