To make good use of advantage of SWDS and heighten the efficiency, using the single trace seismic data from SWDS and common coupling receivers on equal conditions, we designed a coupling match filter by the method of Optimum Wiener Filters.

According to performance analysis of unconstrained phase-only matched filtering function and ECPSDF algorithm,their composite matched filter algorithm is obtained.

In the continuous tracking, using the correlative re-conformation of matching filter, with the subdivision of frequency or phase, a multi-frame processing arithmetic for anti-jamming was put forward.

Computer simulation and experimental results show that matching filter using extracted feature to code can recognize two images of common feature.

The paper provided a way to make the optimization match filter by computer could simplify the experiment scheme and meet the need of real-time recognition.

This paper presents a novel long-period PN-code fast acquisition scheme which is based on "match filter + sequence estimation"approach.

A modified match filter was used to increase the signal-noise ratio(SNR) of 3-20dB.
