Accurate Determination of Baseline in DSC Measurement;

Considering the technology difficulty in satisfying direction finding accuracy and resolving angle ambiguity,the same time in defined space for ultra-band antiradiation missile seeker,theories of direction finding by phase interferometer and resolving angle ambiguity by double base line are simply introduced.

Based on binary valued fingerprint image, statistical window and base line of each region were defined.

The paper focus on the detailed structure of the optical system in helmet mounted electro optical sight scanning system,and makes analysis of the principle error caused by ten side prism reflector non direction fit axis rotation in measuring its head position,it further derives two formulas for base line correction and goniometry correction.

A photoelectric scene adopting indoor examination short basic line and acrial fixed edge is introduced,the characteristics of which are analysed,and the examination accuracy of which is analysed theoretically.

Finally,the contours of GDOP under various conditions in the specific surveillance region and the influence with basic line and the depth and so on are drawn by computer simulation.

Then,the concrete location formulas and error calculating formulas in the location system are presented,and the contours of GDOP with different distribution of the arrays and basic line are drawn by computer simulation.
