The system adopt computer with the picture acceleration card to the real - time process . in the software the system use the fast algorithms to improve the image processing and parameter operating speed
42.
Because of the ability of fpga in real - time processing and the consideration of the use of resource in fpga , small infrared target can be detected in real - time by this method with fpga device
43.
Synthetic aperture radar ( sar ) has the characteristic of all - weather , day / night and long range , so it is of great value to study on real - time processing for sar imaging in both civilian and military applications
44.
Conventional matched filter - based correlator needs to make matched filter in advance , it has many disadvantages : large calculation , slow speed , not suitable for real - time processing , and recognition precision is low
45.
( 2 ) the fft technology applied to frequency estimation algorithm is studied . comparing with some kinds of fft system - on - chip , fpga is the best choice to design fft module , which is to fulfill real - time processing request
46.
Airborne sar imaging system has been widely used and can provide a test platform for space - borne sar system . the study of airborne sar imaging algorithm and real - time processing is very important in remote sensing
47.
At the same time , they process a great deal of data with high rate . these characteristics make them suitable to realize in fpga . pulse compression technology has request of multi - channel and real - time processing when it is applied in software radar
48.
So optical joint transform correlation is proposed . optical joint transform correlation can recognition automatically , conquer drawback of filter - based correlator , and it is suitable for real - time processing , can achieve well recognition
49.
In this paper , the research advances of earthquake early warning system is briefly summarized and the real - time processing technique of strong ground motion parameters is mainly researched the main achievements of this study could be summarized as follows : 1
50.
So optical joint transform correlation is proposed . optical joint transform correlation can recognize automatically , overcome the drawback of filter - based correlator , and it is suitable for real - time processing , can achieve better recognition result
