By combining successiveelimination technique with above method, weak LFM signals can be detected among some strong LFM signals and their parameters are estimated.
In order to reduce the calculation number of matching position and keep the precision, we make use of the successiveelimination algorithm. Therefore, the complexity was reduced.
