PROBLEM TO BE SOLVED: To avoid that an amplitude value of an entire frame becomes high and to avoid that an amplitude of a cell at a periphery of a cell with the high amplitude value becomes high.SOLUTION: A target tracking device comprises: a selection history holding section 2 for holding selection history information in a TBD processing by a TBD processing section 1; a back track re-addition section 4 which performs a back track processing on a high-order cell extracted by the TBD processing section 1 to acquire an addition route by using the selection history information and re-adds a signal by using an observation frame in accordance with the addition route; a signal extraction section 5 for extracting a signal whose re-addition value is higher from the frame processed by the back track re-addition section 4; and a target signal extraction section 6 which integrates the signal extracted by the signal extraction section 5 with a signal whose position of the cell is overlapped and outputs the signal as a target signal.SELECTED DRAWING: Figure 1 |
