Data compression method for aircraft tracking system for military defence purposes, calculates short trajectory by artificial measurement

摘要

Each short trajectory (ST) is calculated by artificial measurement. The artificial measurement comprises calculating the likely 3D position of an object and an estimation of the volume defined by the covariant matrix using an approximately cube-shaped corresponding 3 x 3 accuracy matrix. Locally obtained data is used to estimate a target trajectory (P) and short trajectories are calculated from these locally suggested target trajectories. Independent claims are also included for the following: (a) Platform for compiling a single integrated image using data from different sources, comprising at least one intrinsic sensor, a unit for receiving short trajectories from other platforms and at least one processing node which uses the data compression method and generates a single integrated image using the short trajectories received and the sensor measurements; and (b) Image integration network for compiling a single integrated image using data from different sources, comprising at least two of these platforms.
