The procedure of combined terminal guidance for anti-galley missile is emulated with the proportional guidance and the bimodulus combined datas in the whole system, and the datas are simulated with the reality datas of the ground unimodular terminal guidance sensor.

In virtue of the information of azimuth and its changing ratio coming from the passive acoustic target, the article puts forward an improved algorithm of passive bearings-only localization and tracking in single sensor single target system.

To improve the precision of data processing, a method of the data fusion suitable for the single sensor system is presented.

A mistake of the single sensor data fusion is analyzed.

Wigner-Ville analysis of measurement fluctuating signals of conductance sensor in gas/liquid two-phase flow;

For the water volume fraction measurement of oil-in-water flow,the mathematical model for the forward problem of sensitivity field in the ring-shape four-electrode conductance sensor was analyzed.

An embedded real-time microprocessor MC56F8323 is used for sampling two fluid flowing signals of conductance sensor's output, calculating cross-correlation function of these signals, and finally transferring the flowrate up to the host computer on the ground through RS485.
