摘要：To deal with the large error of burst height measurement for novel optional burst height millimeter wave proximity fuses in new-generation long-range projectiles, a ground object recognition strategy based on echo polarization is proposed in this paper. In the height measurement process, there are many factors, including the flight condition of the projectile, tall objects, ground clutter, interference signals, etc. restricting measurement accuracy. Therefore, a novel measurement scheme is urgently needed to enhance the accuracy of height measurements. The method mainly distinguishes the surface and ground objects within the range of the detected beam, under the condition that the detection area has apparent divisions. The polarimetric rotation-invariant parameters are used to analyze the features of ground objects. On the other hand, when the detection area does not have apparent divisions, the polarimetric echo reconstruction technology is used to determine the surface. Simulation experiments show the feasibility and superiority of the proposed method compared with the traditional height measurement system. Even in the presence of extensive interference, the method allows the accurate measurement of the projectile’s height above the ground.
