Application of cascade matched filtering in mixed source data processing.;

Using matched filtering method based on cosine transform to separate gravitational and magnetic a-nomaly.;

Application of matched filtering technique to 3D achievement data processing of Linyi.;

In particular,the implementation of the matched filtering.

In this paper,we put forward that the radar can transmit the LFM signal with wide band and long time and apply the matched filter to the signal processing to enhance the SNR of the helicopter blade echoes.

In order to detect the object in seabed in underwater acoustic image automatically,a synchro method based on matched filter and fractional detection is proposed in this paper.

Faint signal processing of lidar based on wavelet transform and matching filter;

On the basis of analyzing the signal character of the static infrared-earth-sensor,a new digital signal processing based on matching filter was developed to find horizon information from the signal serial with low SNR.

The signal detection unit of the system is analyzed with matching filters to process the echo signals with idealized results, which plays an important role to the extraction of characteristic signals and the improvement of detection precision.

Frequency filtering can be used to satisfy the condition of matching filtering.

In view of the characters of complex geologic structure,serious static corrections,lower data S/N ratio and difficult to joining the map,using successful experiences of data processing at home,the paper integrated the Key techniques such as denoise and matching filtering and further formed a set of 3-D block-jointed together processing technique suitable for local lower S.
