The performance of detecting weak targets is not fine for active sonar by using the cascaded time-space adaptive method. Based on which, this paper presents a modificed cascaded time-space adaptive method. The new method enhances the performance of active sonar detecting weak targets greatly by means of ODN narrow notch filter that is carrid out by the technology of reverberation primary component...
Reverberation covariance matrix is singular matrix owing to limited sample obtained by active sonar in non-stationarity environment. Based on which, a robust space-time adaptive method is presented in this paper. The new method avoids singular matrix which aroused by small eigenvalue with diagonal loading. In the scenario of limited sample number, the new approache can cancel the reverberation effectively...
Nowadays, Radio Frequency Identification (RFID) technology has drawn great attention in industry and military such as the fields of automatic identification and data collection. An RFID-based equipment management information system(REMIS) was proposed to the aims of keeping allocation under control, taking statistics of strength and inspecting security of equipment more efficiently, automatically...
