Annex E. International Armaments Strategy
Army Science and Technology Master Plan (ASTMP 1997)

4. Acoustic Sensors (Israel)

Description: Acoustic sensor technology involves the use of microphone arrays to detect, locate, track, and identify air and ground target at tactical ranges. Target information from multiple acoustic sensor arrays is digitally transmitted to a remote central location for real-time battlefield monitoring. In addition, acoustic sensors are used to enhance the soldier's long range hearing and detect sniper and artillery fire.

Justification: Current efforts in acoustics include adaptive beamforming algorithms, sound cancellation techniques to eliminate platform and wind noise, and Neural Network algorithms for target identification. Sensor fusion has shown a significant increase in the acoustic detection and ID performance. Advanced helicopter detection, sniper, and mortar location systems are in the final phase of development by the Israelis.

Implementation: A Joint Acoustic Field Experiment has successfully been conducted with the Israeli Army in March 1993 to demonstrate the state-of-the-art in remote needed acoustic detection sensors. Cooperation will provide potential solutions to acoustic propagation problems, long range target detection algorithms, and detection of targets in noisy environments (in the presence of wind and platform noise).
