Abstract

The invention discloses an infrared polarization simulation method for an infrared point source bait bomb. The invention relates to the technical field of aircraft simulation, in particular to an infrared point source bait bomb calibration method, which comprises the following steps of: firstly calculating and determining a standard radiation characteristic curve of an infrared point source bait bomb, segmenting the curve to obtain a plurality of fitting functions, performing bias on parameters in the curve according to bias requirements to obtain bias values, and finally fitting according tothe fitting functions and the bias values to obtain a time domain bias curve. According to the infrared bias simulation method for the infrared point source bait bomb, bias simulation can be carried out on the infrared point source bait bomb, so that a simulation result can be closer to a real scene.

Description
