An effective tracking method is proposed to solve the problem that the electro-optical tracking system in Missile Range easily loses the real target during the target separation. Before target separation
the error correcting value of the theoretical trajectory is obtained by the theoretical trajectory correcting algorithm. In the phase of target separation
the theoretical trajectory of the target is corrected by the error correcting value firstly
and then the fuzzy clustering association algorithm is applied to calculate the similarity between the measuring data of the target from sensors and the corrected theoretical trajectory. The similarity helps to identify whether the measured data is from the real target or not. Experimental results show that the authenticity of the target can be determined effectively. The identified results can be used as the decision-making basis of the servo sub-system and TV trackers
which can improve the continuous tracking probability of the electro-optical tracking system in the target separation. 2010 IEEE.

This paper proposes that the inter-layer separation distance (ISD) and the unit cell aligning error (UAE) are used as main variables to study the transmission performance attenuation of the double layer FSS configuration. The numerical analysis model for ISD and UAE was established and also was used to simulate the cross loop slot cell FSS transmission performance by the finite element and periodic moment method program. The double layer cross loop aperture FSS configuration designed was used as the numerical model. As a result of the numerical analysis
it is shown that both ISD and UAE produce insertion transmission loss (ITL) and insertion phase distortion (IPD) directly. Furthermore
ISD results in much loss of the amplitude of the transmitted signal for the FSS than UAE. It is significant for the designer for the multiplayer FSS to assign the fabricated error of the FSS dielectric layers. The UAE introduces the insertion phase variation badly.

The characteristics and effects of alignment error on test results are analysed in this paper. The mathematical model are established
the least square method is used to determine the misalignment. Procedures are presented that allow for separation of misalignment from misfigure in asphere testing. The misalignment-induced aberrations by corrector and the support of the mirror can be calculated and subtracted from segment interferogram so that only true misfigure remains. The accuracy of the system can reach up to 0.028(=632.8nm).
