The invention provides a secondary surveillance radar track extraction method for multimode polling and S-mold roll-calling interrogation. By using the method, false targets under an interference environment can be effectively removed and the accuracy and the real-time performance of the S-mode query are improved. The method is realized through the technical scheme that plot combination is conducted to S-mode plot data which is searched from the same sector of a secondary surveillance radar interrogator, the mean value and the variance of the plot data are calculated, and a real track is initiated after time-space registration; the combined plot data is divided according to the sector characteristic of radar and an associated sector window is created to enter a plot and track processing flow; firstly de-biased measurement conversion is conducted to the associated plot data, a CV (Constant Velocity) model, a CA (Constant Acceleration) model and a current statistical model are combined into a target multi-model, and the interactive input state estimation vector and the variance of each filter under an interactive effect are calculated; interference targets are removed by adopting interference target removing strategies; and unnecessary target files are removed through track management, tracking is ended and a correct target track extraction result of the secondary surveillance radar is given.

True three-dimensional panoramic display and interactive apparatus without calibration

InactiveCN101231752ANatural movementRealize the real three-dimensional effectImage analysisInterior spaceDisplay device
The invention provides a true three-dimensional panoramic display and interactive device without calibration, which comprises a main support, a helmet-mounted display, an image storage processor and a host computer. The main support is provided with a holder used for installing a plurality of cameras. The cameras are arranged on the holder. An observer standing in the inner space of the main support can watch a virtual scene in real time through the helmet-mounted display. The observer can move freely in the space including turning the head, walking and turning freely. The observer can interact with the scene in real time. The image information of the observer is collected through the plurality of cameras. After images are preprocessed, the host computer analyzes, matches and calculates a plurality of images to get the information of positions, poses and actions of the observer in real time. In this way, corresponding change of the virtual scene in the helmet-mounted display can be controlled to achieve visual display and interactive effect. Without calibrating the observer, the observer can turn the head and body naturally to change the view point, thus achieving true three-dimensional panoramic display and interaction. The invention has the advantages of better immersion and flexibility.

Preparation method of anticorrosive paint of polyaniline modified mesoporous molecular sieve

The invention provides a preparation method of an anticorrosive paint of a polyaniline modified mesoporous molecular sieve and relates to the anticorrosive paint. The preparation method comprises the following steps of: firstly, polymerizing polyaniline in a pore channel of a filler of a mesoporous molecular sieve with a pore channel structure and on the outer surface of a mesoporous molecular sieve grain in situ to obtain a polyaniline coated and modified inorganic filler; then, mixing the polyaniline coated and modified inorganic filler with aqueous epoxy resin and curing to obtain the anticorrosive paint; forming the polyaniline on the outer surface of the mesoporous molecular sieve grain in situ; extending the polyaniline which is polymerized in the pore channel of the mesoporous molecular sieve grain in situ to a pore opening of a mesopore to generate a stronger interface interactive effect with an epoxy resin matrix, so as to increase the compatibility and prevent the nano grains from being clustered in the resin matrix, and also increase the cross-linking density of the coating. The polyaniline has the anticorrosive performance so that the anticorrosive performance of the coating is improved. The content of the polyaniline in the filler is very low, the synthesis process is simple and the anticorrosive paint does not need to be dissolved and can be directly used, so that the use is convenient and the cost is low.
