| Along with the developing of the electronic test ground,the task performed by electronic test ground is changed from traditional precision test to electronic counter measure test,and then,the types of data need to be acquired is getting more and more,and the amount of data acquired in test is getting larger and larger. When we evaluate the disturbed effect in ECM's test,In order to ensure that we can make exact commands immediately and get the exact evaluation of disturbed effect,it does the special significance that obtaining the disturbed Radar's echo-video signal and redisplay the signal in real time. On the base of measuring the Radar's video-signal,we in-depth study and analysis the video-signal in this subject,we find out every techno-parameter's items of sampling video-signal,and then research the effect bringing out by sampling. We originally put forward the system solve project of sampling,transmitting and recording the measuring Radar's video-signal. We have performed the integration of the system,and have accomplished the programming of sampling software and data's transmitting software,in the OS platform of Windows 98 and Windows NT and in the programing environment of Visual C++. Had successfully solved the data sampling problem,data transmitting problem and data displaying problem by multi-thread programming and data compression technology.The manufacture has character of practicability and expansibility,and has arrived at the applying request of test ground. |
