Embodiment Construction
[0017] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0018] Such as figure 1 As shown, the present invention is based on the embedded platform adaptive filtering target tracking and positioning method comprising the following steps:
[0019] Step 1: Use the input interface module to obtain the current geographic location observation data of the target aircraft through the data bus of the ARM embedded platform. The geographic location observation data is in a fixed-point format. First, convert the geographic location observation data into a floating-point format. If the information source is the observation data obtained in the earth-centered polar coordinate system, it is first transformed into the earth-centered rectangular coordinate system by vector operation. In order to meet the needs of practical applications, two versions based on ...
