RCS Weighted Filtering Method Suppresses Target Angle Flicker

The relationship between RCS and target Angle flicker was established, and the calculation model of angle flicker suppression by weighted filter algorithm is established. The model is used to process and compare the simulation data and the measured data respectively, the results shows that the target RCS weighting method is suitable for suppressing target angular flicker. The angle measurement accuracy of radar can be improved by using RCS weighting method. The results show that the method can accurately determine the moment of extinction of the bottom row of projectiles. The method can also be used to determine the moment of ignition or extinction of other types of projectiles.
