The reconnaissance satellite
communication satellite and navigation satellite used in the military applications have played more and more important role in the advanced technique wars and already become the significant support and aid system for military actions. With the development of all kinds of satellites
anti-satellite laser weapons emerge as the times require. The experiments and analyses of laser disturbing CCD (charge coupled detector) in near ground have been studied by many research groups
but their results are not suitable to the case that using laser disturbs the satellite-based detector. Because the distance between the satellite-based detector and the ground is very large
it is difficult to damage it directly. However the optical receive system of satellite detector has large optical gain
so laser disturbing satellite detector is possible. In order to determine its feasibility
the theoretical analyses and experimental study are carried out in the paper. Firstly
the influence factors of laser disturbing satellite detector are analyzed in detail
which including laser power density on the surface of the detector after long distance transmission
and laser power density threshold for disturbing etc. These factors are not only induced by the satellite orbit
but dependence on the following parameters: laser average power in the ground
laser beam quality
tracing and aiming precision and atmospheric transmission. A calculation model is developed by considering all factors which then the power density entering into the detector can be calculated. Secondly
the laser disturbing experiment is performed by using LD (laser diode) with the wavelength 808 nm disturbing CCD 5 kilometer away
which the disturbing threshold value is obtained as 3.5510-4mW/cm2 that coincides with other researcher's results. Finally
using the theoretical model
the energy density of laser on the photosensitive surface of MSTI-3 satellite detector is estimated as about 100mW/cm2
which is largely exceed the disturbing threshold and therefore verify the feasibility of using this kind of laser disturbing the satellite-based detector. According to the results. using the similar laser power density absolutely saturate the requirements to laser disturbing satellite-based detector. If considering the peak power of pulsed laser
even decrease laser average power
it is also possible to damage the detector. This result will provide the reliable evidences to evaluate the effect of laser disturbing satellite-based detector. 2009 SPIE.
