Abstract

Abstract:

In the design problem of low earth orbit (LEO) reconnaissance satellite constellation, optimization of coverage performance is the design goal in most current methods. However, in the using process, the user only concerns with the detection capabilities rather than coverage performance. To establish the relationship between these two aspects, the reconnaissance processes of normal stochastic targets are considered and the mathematic models of detection processes are built. The indicators of coverage performance are used to evaluate the detection probability and expectation of detection time delay, which are important factors in reconnaissance constellation estimation viewed from military intelligence discipline. The conclusions confirmed by the final simulation will be useful in LEO reconnaissance constellation design, optimization and evaluation.

Key words: low earth orbit (LEO) reconnaissance satellite constellation, detection capability, Monte Carlo experiment
