Embodiment Construction

[0080] The present invention will be further described below in conjunction with accompanying drawing: the present embodiment is carried out under the premise of technical scheme of the present invention, has provided detailed embodiment and specific operation process, but protection scope of the present invention is not limited to following implementation example.

[0081] This section takes the airborne radar system error estimation and compensation as an embodiment description, and this embodiment includes the following steps:

[0082] The first step is to check the data of cooperation targets and non-cooperation targets by division; specifically,

[0083] Divide the sensor detection space into N areas according to certain rules, and set two storage areas for each area: cooperative target area and non-cooperative target area. Store the data in the corresponding area according to the target measurement data and whether the target is a cooperative target.

[0084] The secon...

Abstract

The invention provides a system error estimation and compensation method for an airborne sensor based on a cooperative target. The method comprises the steps of firstly constructing a system error equation by using self-positioning information of the cooperative target and observation data of the airborne sensor, which is acquired by observing the cooperative target; then estimating a system error obtained by summing measurement system deviation and attitude deviation by an equivalent method and an adaptive filtering technology; finally performing partition compensation on measurement data of a non-cooperative target. An experiment shows that the system error estimation and compensation method is high in robustness, high in reliability, low in calculation complexity and particularly suitable for engineering practice.

Description

technical field [0001] The algorithm of the invention relates to data fusion technology, in particular to sensor space registration technology, and specifically refers to an airborne sensor system error estimation and compensation method based on cooperative targets. Background technique [0002] Modern warfare is faced with a complex and diverse external environment, and it is difficult for a single sensor to meet the needs of battlefield information analysis. More and more practice has proved that using a multi-sensor system to select an appropriate algorithm to fuse and process multi-source information can obtain more useful information than a single sensor. Compared with the single-sensor system, the multi-sensor system enhances the survivability of the system, expands the time coverage domain and space coverage domain, and improves the credibility of information. However, the crucial premise for these advantages is to be able to accurately solve a series of key problem...
