To determine the feasibility and practicability of interrupt continuous wave (CW) approach proposed for real time simulating radar intermediate frequency(IF) video signal, theoretical analysis and computer simulation were used.

Design of video signal acquisition system based on CPLD and SDRAM;

Numeral video signal processing system based on FPGA+DSP;

Design of remote multi-center video signal wireless transfers and data acquisition system;

The video-signal which is outputted by CCD serves as the input of the comp.

According to the practical analysis,a new program is introduced,which solves the problem that the system can only transmit the voice,but not transmit the video-signal.

For image with tendency to binary value,the way is introduced on how to realize video signals sampling and synthesis with the use of interruption triggered by row synchronization pulse signal and time series logical circuit at the core of the STC89C516RD.

Technique analysis of GPS IF signal rapid acquisition;

Design and Implementation of Pulse Radar IF Signal Acquisition and Recording System;

The speech signal jamming effect objective evaluate method and digital communication base band jamming effect evaluate method and IF signal evaluate method of a communication system were introduced.
