Embodiment Construction
[0037] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0038] The present invention provides a method for simulation and analysis of space debris laser ranging effects. The preliminary analysis and actual use process of the method are as follows:
[0039] Step 1. Substitute parameters such as space debris material reflectance, distance, and atmospheric transmittance into the space debris echo photon number equation to obtain the echo photon number and estimate the echo photon distribution; according to the skylight background brightness, detector dark noise and other parameters Estimate the amount and distribution of noise.
[0040] Among them, it is considered that the echo distribution obeys the Gaussian distribution, and the noise distribution obeys the uniform distribution. Non-cooperative targets such as space debris only rely on their surface diffuse reflection characteristics to reflect laser light, an...
