Abstract

Passive detection systems guarding battle space, often called Unattended Ground Sensors (UGS) in publications, have been utilised in military applications for several years experiencing a number of changes and updates in design recently. Their primary task is to detect and identify the targets of interest that may be defined as personnel, wheel or track vehicles or other type. As standard, seismic, magnetic, passive infrared, acoustic or other sensors are used for detection and identification, if applicable. UGS systems then digitally process and evaluated the signals generated by the sensors. The submitted paper explains signal digital analysis and the options for detecting low-flying targets through surface seismic wave utilisation. It contains mathematical description of and the results from processing the surface seismic waves excited by some types of aircraft flying at low ground altitudes. It also mentions the options for low-flying target identification and suitable type descriptor selection. The processed results are presented in table and diagram forms created in Matlab mathematical environment. All the presented detection and identification results were obtained from real recorded signals.
