<p>PURPOSE:To enable execution of stable tracking even under the effect of clutter, by selecting track data found in a radar coverage area wherein a computed erroneous search rate is the lowest, when track data of which errors are within prescribed values are inputted. CONSTITUTION:In an error verifying element 5, track data A and B detected by a search of a radar are compared with estimated data on a track stored in a track file 2 and thereby it is verified whether errors of the data A and B are within prescribed values or not, in other words, whether they meet the standard of verification or not. Next, in a data selecting element 7, the data of which the error is reckoned as meeting the standard of verification by the verifying element 5 are selected from the data A and B. When there are two inputs, the data A and the data B, for instance, the data A or the data B which are found in a coverage area wherein an erroneous search rate computed by an erroneous search rate computing element 6 is lower are selected. When the erroneous search rate in the coverage area wherein the data A are found is 3% and the erroneous search rate in the coverage area wherein the data B are found is 5%, in other words, the data A are selected.</p> |
