Fast scan‐to‐scan integration algorithm for small target in sea clutter

Abstract: For small slowly moving targets detection in spiky sea clutter, a fast scan-to-scan integration preprocessing algorithm is proposed. By introducing a velocity steering vector, the scan-to-scan integration is achieved by matrix operations instead of traditional target path searching algorithms. The concept is demonstrated using measured data collected from an airborne maritime surveillance radar. Results show that the computation complexity of the back-end track-beforedetect block can be reduced by two orders u… Show more

“…And then, the interscan binary integration using the retrospective filter bank (RFB) is used for final decision. In [19], the generalized likelihood ratio test with linear threshold detector (GLRT-LTD), which is the optimum coherent detector in compound-Gaussian sea clutter with the inverse Gamma-distributed textures [40], is used as the intrascan processing to generate the plot data, their test statistic and Doppler offsets. Stacking these data on the range-scan time plane in the interscan processing, the three features are extracted by the integration using the Dopplerguided retrospective filter for final decision.…”

“…Yang et al [30] emphasized on employing Butterworth high-pass filter so as to detect a small (slowly moving) target. Jin et al [31] gave more preference to the Velocity Steering Vector (VSV) than the classical searching approaches to perform small slowly moving targets detection in spiky sea clutter.…”
