Abstract:
A track-before-detect(TBD) algorithm is efficient for weak target detection,so it can be used for increasing the maximum radar range. But the application of TBD is restricted because of its large computation. Considering to reduce the elapsed time of TBD, a improved dynamic programming based TBD algorithm is presented, in which the states are reduced by using CFAR processing and the detect probability is excellent by alternate-frame paths researching in addition to recursion phase. Monte-Carlo simulation results show the method is rapid with good detectability.
