In this paper, we propose a new method to solving the phase difference variety ambiguity by using stagger distance difference after analysis of the phase difference.

For the sampling bandwidth to be reduced, ISAR echoe s are usually dechirped at the receiver with the reference range varying according to the target position at each pulse.

Zadeh,infeasibility of maximum membership degree law,influence of distance parameter in Fuzzy optimization and defect of liner weight average model in Fuzzy judge are discussed.

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.

The distance factor and distance dispersion factor are presented.
