Operating principle of laser beam-riding guidance was set forth. Based on the principle of spatial frequency-encoding  experimental results demonstrated that the receiver can receive correctly the encoded signal and can decode the signal  an optimum laser encoding mode was designed  measurement for the missdistance is feasible and all the performance parameters satisfy the demand. (2012) Trans Tech Publications  which can transfer continuous laser into pulse laser that represents different position information. Then the mathematic model of deviation from target is built  Switzerland.  a modified encoding pattern was presented  which is composed of two light paths crossed 90. Azimuth information of target is given in orthogonal coordinate system and deviation from target is linearity. As well as  characteristic distribution of spatial laser field is analyzed. Corresponding decoding mode was presented  by testing in 2 kilometers outdoor

As a result of the radar system got interferenced or in the state of half silent  it can cause the guided precision drop badly In the modern electronic warfare  therefore it can lead to the equipment depended on electronic guidance cannot strike the incoming goals exactly. It will need to rely on optoelectronic devices to make up for its shortcomings  but when interference is in the process of radar leading  especially the electro-optical equipment is influenced by the roll  pitch and yaw rotation  it can affect the target appear outside of the field of optoelectronic devices for a long time  so the infrared optoelectronic equipment can not exert the superiority  and also it cannot get across weapon-control system "reverse bring" missile against incoming goals. So the conventional ship-borne infrared system unable to track the target of incoming quickly  the ability of optoelectronic rivalry declines heavily.Here we provide a brand new controlling algorithm for the semi-automatic searching and infrared tracking based on inertial navigation platform. Now it is applying well in our XX infrared optoelectronic searching and tracking system. The algorithm is mainly divided into two steps: The artificial mode turns into auto-searching when the deviation of guide exceeds the current scene under the course of leading for radar.When the threshold value of the image picked-up is satisfied by the contrast of the target in the searching scene  the speed computed by using the CA model Least Square Method feeds back to the speed loop. And then combine the infrared information to accomplish the closed-loop control of the infrared optoelectronic system tracking. The algorithm is verified via experiment. Target capturing distance is 22.3 kilometers on the great lead deviation by using the algorithm. But without using the algorithm the capturing distance declines 12 kilometers. The algorithm advances the ability of infrared optoelectronic rivalry and declines the target capturing time by using semi-automatic searching and reliable capturing-tracking  when the lead deviation of the radar is great. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

A key problem of attitude measurement of small-multi-target with high speed is how to decide the optimum of the CMOS stations. A multi-CMOS station mode is designed in this paper  multiple CMOS videos were placed on two parallel sides in measurement system  every two CMOS form an intersection viewing field  multiple viewing field join to cover shooting range  which can augment Effective Viewing Field(EVF)  increase capture ratio of objects with high speed and measurement precision of small objects. When an object passes through the joint area  it will be imaged separately on each CMOS focal plane. Multiple CMOS videos were triggered synchronously  a sequence of image information was extracted  the target attitude was confirmed by digital image processing technology. The merit of station mode is low cost  large measurement scope  extending freely and so on. 2010 IEEE.

A line-of-sight (LOS) Locating algorithm for staring imaging is presented in this paper. Staring imaging is an imaging mode for aerial remote sensor  which photographs the designated earth-fixed target in muItidirections. Therefore  the details of interesting targets is available. For the target obscured or disguised  its advantage becomes more apparent. This paper proposes the method using two-axis rotation to achieve staring imaging  and establishes the system model and the associated coordinates. Adopting the method of coordinate transformation  the LOS Locating algorithm is constructed  which determines the LOS direction. For the validation of algorithm  Target Geolocation Algorithm is established using Simulink library blocks. Eventually  it proves the feasibility of the LOS Locating algorithm. This article provides a thought of LOS Locating algorithm for staring imaging. The method of coordinate transformation used in this paper can be applied to line-of-sight positioning in other imaging modes. 2010 IEEE.
