| description | The target angular glint is the main factor restricting the tracking accuracy of radar at close range. There are few researches on angular glint of pulse compression radar. Here, the angular glint model of the large aerodynamic target under pulse compression is proposed. The field measured data verify the validity of the model. Second, a frequency-diversity algorithm based on gating weighting is proposed to suppress angular glint. Simulation results show that its performance is better than the traditional frequency diversity algorithm. Third, the influence of total frequency hopping bandwidth and number of hopping on the frequency diversity algorithm is discussed. Finally, the algorithm proposed here has been applied with the existing experimental prototype. The outfield experiments show that the algorithm can suppress angle glint noise effectively. |
