Field testing of new unattended small size seismic module for various target detection

Abstract

General Sensing Systems (GSS) has achieved outstanding and verifiable results in the design and performance of seismic systems with near zero false alarm rates for the detection of walking and running persons. These results were realized in a number of detection systems and in particular in small size seismic detection modules. Preliminary testing of these seismic modules in various environment noise conditions shows that such small unattended modules can be successfully used for other target detection. Potential target sets can include light and heavy vehicles, helicopters, aircraft, and ships. This paper describes preliminary results of such target detection and preliminary experimental data about corresponding detection range. We show that the new unattended, small size detection module demonstrates reliable performance in various environment conditions.

A New Identification Method of Underground Excavation Based on Velocity Estimation Using Double Point Synchronous Measurements

“…Then, the upper and lower bounds of the target speed confidence interval can be deduced by using formula (16), where the upper bound is formula (17).…”

“…If the activity caused by personnel walking within the monitoring area is detected as digging behavior, then a false alarm will result. Moreover, if a person walks in the monitoring area while underground excavation is taking place, the system may determine that a person is simply walking in the monitoring area, which could cause a missed alarm [16], [17].…”

Алгоритм Идентификации И Определения Курса Движущейся Ненаблюдаемой Бронетехники

“…В работе [6] были исследованы частотные характеристики сейсмоакустических волн, образующихся при движении со скоростью ~30 км/час легких (весом 1-10 тонн), средних (весом 10-20 тонн) и тяжелых (весом >20 тонн) машин. Было установлено, что дистанция обнаружения скрытого движения техники сильно зависит (прямо пропорционально) от шероховатости грунта, скорости и веса Перспективні технології в оборонній сфері Наука і оборона 1'2017 машин и может достигать до 1000 метров и более.…”

“…О бнаружение, локализация и идентификация наземными средствами удаленной на несколько километров движущейся в горной местности ненаблюдаемой тяжелой бронетехники является одной из актуальных задач военной науки. Решению этих вопросов посвящено много работ [1][2][3][4][5][6][7].…”

Advanced seismic signal processing techniques for detection and bearing estimation of footsteps and vehicular signals

“…The research focus is now shifted from detection of surface sources to estimating the bearing angle of the detected sources. Bearing estimation is an important attribute of outdoor surveillance systems since it provides source localization and tracking capabilities [11,104,105]. Most of these security systems utilize multiple geophones and achieve localization either by evaluating the signal energy to determine the vicinity of the source to a particular sensor node [106] or by evaluating the time-difference-of-arrival between the sensors [11].…”
