This paper focuses on the issue of CCD remote sensing image compression. Compared with other images,
CCD remote sensing image data is characterized with high speed and high quantized bits. A high speed CCD
image compression system is proposed based on ADV212 chip. The system is mainly composed of three
devices: FPGA, SRAM and ADV212. In this system, SRAM plays the role of data buffer, ADV212 focuses
on data compression and the FPGA is used for image storage and interface bus control. Finally, a system
platform is designed to test the performance of compression. Test results show that the proposed scheme can
satisfy the real-time processing requirement and there is no obvious difference between the sourced image and
the compressed image in respect of image quality.
With the rapid development of semiconductor technology and laser technology, a kind of proximity fuze named
pulsed laser proximity fuze has been applied. Compared with other fuzes, pulsed laser proximity fuze has high ranging
precision and strong resistance to artificial active interference. It is an important development tendency of proximity fuze.
The paper analyze the characteristic of target echo of laser signal, and then make theoretical analysis and calculation on
the laser signal transmission in the smog. Firstly, use the pulse width of 10ns semiconductor laser fuze to do typical
targets experiment, to get the echo information of target distance is 5m; then to do smog interference experiment, by
comparing the pulse width amplitude and backscattering signal amplitude of laser fuze in simulation and experiment,
analyzing the effect of anti-clutter, providing the evidence for the subsequent of circuit of signal amplification and
