RCS Sequence Period Estimation Method Based on Constant False Alarm Detection

摘要

1 Introduction In the Radar Cross Section (RCS) sequence of periodic targets [1], there is a unique periodic phenomenon as shown in Fig. 1, which is due to the periodic phenomenon caused by the target roll or the periodic motion of the target component. Although this type of RCS sequence has obvious periodic phenomena, it cannot be extracted by spectrum analysis tools. For this kind of data, this paper proposes a target period discrimination method based on Constant False Alarm Rate (CFAR) detection.
