The invention discloses a method for achieving three-dimension positioning of a non-cooperative double
multistatic radar target. The method belongs to the technical field of passive double
multistatic radar target positioning. In a non-cooperative double
multistatic radar, an existing target position estimating method based on the iterative optimal
algorithm has the defect that due to the non-
linear relationship between a target position and double base parameters, if the initial value is not properly selected, a wrong solution can be obtained and in addition, the iterative
algorithm consumes lots of time. Thus, the invention provides the method for obtaining an analytical solution of a three-dimension position of the non-cooperative double multistatic
radar target. The method integrates measuring of multiple pairs of transmitters and receivers and deduces the analytical solution of the three-dimension position of the target through a model of minimal target
position error vectors of the target position. The method for achieving three-dimension positioning of the non-cooperative double multistatic
radar target is fast in arithmetic speed, suitable for a double multistatic
radar system to perform target positioning, wherein the double multistatic radar
system carries out opportunity detecting based on all sorts of opportunity illuminators.
Initiation of a target track is facilitated and a better result can also be obtained under the multiple-target environment.
