TMA - Range Rate and Target Zig

04-21-10, 12:49 PM

Consider this case:
I have a solution on the target accurately and in a LOS LAG, ownship Route 90 and Route 270 ° Target. At time t1 the Target zig. Calculating the Range Rate for all Bearing in order to have a history of the Range Rate, Target is the zig to the right or left, the range rate increases, how can I guess which side has zig?
If I had the accurate calculation of the Bearing Rate this problem did not exist, unfortunately Bearign Rate calculated from DW refers to the solution we estimated. : (
In TopTorp manual shows that the range rate can know which side has the zig Target, but how to get a Range error rate that is linked with the zig Target ?????
