specific Embodiment approach 1
[0066] Specific implementation mode one: refer to figure 1 Specifically explaining this embodiment, the detection mode and accuracy analysis method of split guidance described in this embodiment includes the following steps:
[0067] Step 1: According to the triangular configuration relationship between the tracker, the observer and the target in the split guidance scenario, deduce the indirect solution equation of the tracker guidance information and its solution error sensitivity;
[0068] Step 2: Quantitatively analyze the reachable detection configuration according to the separation and interception characteristics of the split guidance;
[0069] Step 3: According to the existing space detection technology, propose several detection modes with potential application value;
[0070] Step 4: According to the analysis results of the solution error sensitivity and the reachable detection configuration, the detection accuracy analysis method of split guidance is obtained, and t...
specific Embodiment approach 2
[0071] Specific embodiment 2: This embodiment is a further description of the specific embodiment 1. The difference between this embodiment and the specific embodiment 1 is that the guidance information in the step 1 includes the relative distance information between the tracker and the target. r ct and inertial line-of-sight angular velocity information The indirect calculation method of guidance information is as follows:
[0072] For the "side-angle-side" triangle construction method, if r ot 、r co and the observer-centered configuration angle (π-q ot -q co ) is given, the triangular relationship between the tracker, the observer and the target can be uniquely determined. According to the law of cosines, it can be deduced that r ct The first solution equation for is expressed as:
[0073]
[0074] Among them, r ot is the relative distance between the observer and the target; q ot is the inertial sight angle of the target relative to the tracker; r co is the re...
specific Embodiment approach 3
[0090] Specific embodiment three: This embodiment is a further description of the specific embodiment two. The difference between this embodiment and the specific embodiment two is that the error sensitivity of the guidance information in the step one is:
[0091] Analyzing the solution error sensitivity of the guidance information, and on this basis, considering the combination separation and target interception constraints of the split guidance, analyzing the reachable detection configuration of the split guidance; analyzing the tracker guidance information r ct Analysis of the solution error sensitivity. According to the tracker guidance information r ct The first solution equation of , get r through theoretical derivation ct The solution error sensitivity expression of can be expressed as:
[0092]
[0093] In the formula, r is the guidance information of the tracker in the first solution mode ct Resolution error sensitivity for each measurement message. It can be...
