A Knowledge-based High Voltage Power Tower Identification Method for SAR

In this paper, a high voltage power tower identification method is proposed by exploiting the prior knowledge. Firstly, several knowledge expression methods for SAR identification are presented, in which the ways to make use of knowledge to improve identifying results are illustrated. Afterwards, the prior knowledge based high voltage power tower identification method for SAR is presented. By utilizing the circumstance high voltage power tower appears, a prior knowledge based CFAR is given. What's more, by making use of the knowledge of high voltage towers' structure feature and periodically appearance, the identification and classification of high voltage power tower in SAR is proposed. Finally, experiments are conducted on both simple and complex real measured SAR to validate the effectiveness of the proposal.
