To deal with the large error of burst heightmeasurement for novel optional burst height millimeter waveproximity fuses in new-generation long-range projectiles, aground object recognition strategy based on echo polarization isproposed in this paper. In the height measurement process,there are many factors, including the flight condition of theprojectile, tall objects, ground clutter, interference signals, etc.restricting measurement accuracy. Therefore, a novelmeasurement scheme is urgently needed to enhance theaccuracy of height measurements. The method mainlydistinguishes the surface and ground objects within the range ofthe detected beam, under the condition that the detection areahas apparent divisions. The polarimetric rotation-invariantparameters are used to analyze the features of ground objects.On the other hand, when the detection area does not haveapparent divisions, the polarimetric echo reconstructiontechnology is used to determine the surface. Simulationexperiments show the feasibility and superiority of the proposedmethod compared with the traditional height measurementsystem. Even in the presence of extensive interference, themethod allows the accurate measurement of the projectile’sheight above the ground.
