In order to get angular velocity of stabilization servo mechanism from angular position sensors
-- filter and its angular velocity transfer function were predigested. Combing with optimum parameters
-- filter based on high sampling rate was established
the effect of and sample rate on filter nature frequency were evaluated. According to the requirements of stabilization platform
the principle of steady and transient tracking filter differential were proved. With the hypothesis of constant acceleration
the frequency characteristics of angular velocity transfer function were analyzed
three-dimensional Kalman filter was simplified
and the filter parameters were designed. The results show that when the spectrum of input signal was lower than 6rad/s
parameters was 0.02
and sampling period were 0.08ms and 0.1ms respectively
the filter can realize differential exactly
when the spectrum was 9rad/s
the precision was no less than 1.1%
the phase leading of angular position was no less than 70
the natural frequency should be higher than the cut-off frequency of stabilization platform was two or three times. In the engineering of electro-optical stabilization servo mechanism
-- filter has properties of tracking differential
and reached the requirement of platform angular velocity estimation. Also it is one of the effective methods to get angular velocity from angular position sensors. 2011 IEEE.

In order to get high resolution
the field of view is 4. Analyzed the imaging
a optical system of golay-3 synthetic aperture telescope has been designed which adopt Fizeau multi-telescope frame. The angular magnification of sub-aperture is -4
the fill factor is 113. The configuration of light beam combiner is Cassegrain style added a lens. The total focal length is 6000mm
the PSF have been improved remarkably
and the cut-off frequency of MTF is close to that of full aperture. 2010 IEEE.
