Abstract
The invention relates to the technical field of radar detection, in particular to a method for radiation calibration of airborne hyperspectral imaging LiDAR system. The method comprises the following steps: S1. A monochromator in a spectrum calibration system emits optical signals of different spectrum values to scan the radar system, thus to obtain the bandwidth and central wavelength of each channel in the radar system; S2. According to the return signal power P(λ, z) in the hyperspectral LiDAR equation and the optical power P(λ) received by the target surface of the detector in the radar system under experimental conditions, a white diffuse reflection board is taken as the ground object target, and a ranging channel is used to measure the flying height of the radar system, thus to obtain the parameters in the return signal power P(λ, z) and the reflection spectrum β(λ).
