Currently
the IR cameras are broadly used in the optic-electronic tracking
optic-electronic measuring
fire control and optic-electronic countermeasure field
but the output sequence of the most presently applied IR cameras in the project is complex and the giving sequence documents from the leave factory are not detailed. Aiming at the requirement that the continuous image transmission and image procession system need the detailed sequence of the IR cameras
the sequence measurement system of the IR camera is designed
and the detailed sequence measurement way of the applied IR camera is carried out. The FPGA programming combined with the SignalTap online observation way has been applied in the sequence measurement system
and the precise sequence of the IR camera's output signal has been achieved
the detailed document of the IR camera has been supplied to the continuous image transmission system
image processing system and etc. The sequence measurement system of the IR camera includes CameraLink input interface part
LVDS input interface part
FPGA part
CameraLink output interface part and etc
thereinto the FPGA part is the key composed part in the sequence measurement system. Both the video signal of the CmaeraLink style and the video signal of LVDS style can be accepted by the sequence measurement system
and because the image processing card and image memory card always use the CameraLink interface as its input interface style
the output signal style of the sequence measurement system has been designed into CameraLink interface. The sequence measurement system does the IR camera's sequence measurement work and meanwhile does the interface transmission work to some cameras. Inside the FPGA of the sequence measurement system
the sequence measurement program
the pixel clock modification
the SignalTap file configuration and the SignalTap online observation has been integrated to realize the precise measurement to the IR camera. Te sequence measurement program written by the verilog language combining the SignalTap tool on line observation can count the line numbers in one frame
pixel numbers in one line and meanwhile account the line offset and row offset of the image. Aiming at the complex sequence of the IR camera's output signal
the sequence measurement system of the IR camera accurately measures the sequence of the project applied camera
supplies the detailed sequence document to the continuous system such as image processing system and image transmission system and gives out the concrete parameters of the fval
lval
pixclk
line offset and row offset. The experiment shows that the sequence measurement system of the IR camera can get the precise sequence measurement result and works stably
laying foundation for the continuous system. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

In this paper
the Electro-optical Countermeasure Hardware-in-the-loop simulation system is introduced
which highlight to problem: real-time control and acquisition of communications data. We discuss the real-time mechanism by the combination of HLA time management mechanism for real-time data communication and out clock
and the double buffer of the acquisition method which ensures high frequency real-time data communications and high data reliability
integrity. The tested data is shown that the Electro-optical Countermeasure Hardware-in-the-Ioop simulation system work properly. 2010 IEEE.

A computer control system is proposed which is based on hardware-in-loop(HWIL) simulation test system. As an important sub-system in simulation test system
the reality is the focus of the simulation system. The construction of the computer control system for laser warning based on HLA Distributed Simulation. By combining the outer clock and time stamp for data frame
data interaction is triggered by outer clock
the simulation process is propelled. The simulation terminal devices are also controlled by the outer clock. The simulation test is done by the above method. The result shows that the data interaction time less than lms
and it meet the need of reality for control
so it is effective. 2010 IEEE.

CCD noises and their causes are analyzed. Methods to control these noises
such as Correlated Double Sampling (CDS)
filtering
cooling
clamping
and calibration are proposed. To improve CCD sensor's performances
the IC
called Analog Front End (AFE)
integration of CDS
clamping
Programmable Gain Amplifier (PGA)
offset
and ADC
which can fulfill the CDS and analog-to-digital conversion
is employed to process the output signal of CCD. Based on the noise control approaches
the idea of chip design of linear CCD drive pulse generator and control interface is introduced. The chip designed is playing the role of (1) drive pulse generator
for both CCD and AFE
and (2) interface
helping to analysis and transfer control command and status information between MCU controller and drive pulse generator
or between global control unit in the chip and CCD/AFE. There are 6 function blocks in the chip designed
such as clock generator for CCD and AFE
MCU interface
AFE serial interface
output interface
CCD antiblooming parameter register and global control logic unit. These functions are implemented in a CPLD chip
Xilinx XC2C256-6-VQ100
with 20MHz pixel frequency
and 16-bit high resolution. This chip with the AFE can eliminate CCD noise largely and improve the SNR of CCD camera. At last
the design result is presented.
