Based on the existing study of incoherent dual point-source counteracting anti-radar missile (ARM),the attacking process of ARM was researched through analyzing the homing and moving theory of ARM,and the error distance of ARM disturbed by dual point-source was probed into.

And then the error distance of ARM disturbed by dual point-source was probed into.

New manipulator calibration method based on screw theory and distance error;

In order to improve the precision while the new system corrects distance error,a new method was proposed by error analysis and emulation computation.

Constraint equations were constructed by using distance error model,and the actual geometric parameters of the robot were solved,and then these parameters were used in the modified kinematics model.

Method of error separation based on photoelectric sensor in measurement of cylindricity;

The evolution forms of a multistep method for roundness error separation and their harmonic restraint analysis;

Angle Indexing Error Separation Technique for Prism--Multi-displacement Method;

A technology of dynamic measure round error and error separating;

The part is evaluated using the techniques such as curve matching, curved face matching and error separating.

The results of the paper is significant in error analyzing of dynamic calibration of systems using step-function signals as the input.
