A novel nerve agent sensor based on surface acoustic wave (SAW) technology was developed and used to detect Sarin in this work. The synthesis and characterization of the coating material of fluorinated hyperbranched polymers werereported. The test results showed that the polymer-coated sensors had the advantages of fast response, high sensitivity, good linear corresponding, suitability for the continuous and real time detection, and the detection limits were up to 0.08 mg/m3.

The calibration of the bias of on-orbit HRG was researched with two proposed methods: calculation with orbit and Kalman filter. When the attitude directing was fixed, calculation with orbit could be adopted. When accurate mathematic model was known, Kalman filter could be adopted. Calculation with orbit needs less condition and was more operable, but calibration precision was worse than Kalman filter. The precision of calculation with orbit could be improved by filtering. The fact proved the feasibilities of the two methods. ©, 2014, Sichuan Institute of Piezoelectric and Acoustooptic Technology. All right reserved.
