III Acoustic Gunshot detector
The latest version of the Boomerang acoustic sniper detection
system operates on stationary or moving vehicles (up to 60 mph),
detecting fire sources by processing the gunshot's haracteristic
acoustic signature, determining the relative shooter's bearing,
elevation and distance. Boomerang III usually processes a gunshot
solution within less than a second. To minimize false alarms,
the system responds only to gunshot trajectories passing within
30 meters of the sensor mast and shooters firing at maximum
effective weapons ranges. The system also filters gunshots fired
from the vehicle, signals picked from road bumps, door slams,
vehicle backfires, firecrackers, wind effect and radio noise
Multi-user Panoramic Synthetic Vision System (MPSVS) from EDO
360 visual situational awareness for crew collaboration and
threat engagement. The system uses multiple video cameras installed
in a ring mount attached to the base of standard CROWS
weapon stations. The system enables the crew to remain 'buttoned
up' while being fully visually aware and engaged. The system
provides 360 stereo 3D images in day and night, under all visibility
conditions. A unique capability offered by the system is the
use of video change detection for route clearance missions,
where previously collected video streams 'change detection'
algorithms are employed to past (recorded) and live feed, detecting
suspicious objects along the route of march.
MPSVS can be integrated with counter-sniper systems such as
the Boomerang III, to facilitate effective sniper engagement.
It also performs passive target designation, which can be use
to direct the weapon station or remote weapons. The panoramic
coverage enables the crew to constantly survey their perimeter,
regardless of the weapon's line of sight. They can track multiple
targets simultaneously in queue for engagement by the weapon
station. The system has an integral 'combat playback' capability,
enabling review of critical events, allowing for the identification
of suspicious elements in real-time or during debrief.
HV from ODF Optronics
Another omni-panoramic vision system was displayed by ODF Optronics
through their US representative Mistral. The system uses multiple
cameras integrated in a bulky sensor pod installed on the vehicle's
roof. The system includes four to six cameras and a single,
rotatable high resolution camera, which provides 'close-up'
viewing of targets of interest. The capture of the omni-directional
scene is performed simultaneously from all cameras, staring
over a 360 deg. without the need to rotate an imaging device.
The system, an evolution of the omni-panoramic
mast-mounted camera introduced in 2004, enables multiple
users to watch the vehicle's surroundings simultaneously, each
with a specific region of interest or allows for single user
surrounding assessment. The rapid 'stitching' of pictures, performed
in real time and on the move, require significant image processing.
Pre-processing is performed on the sensor pole while the remaining
is performed on the system's 'black box' or operating computer,
which can also be utilized for video motion detection, enabling
perimeter protection for 'silent guard' mission, offer obstacle
avoidance when driving or reversing in narrow urban terrain
and offering 'close-up' views of specific areas of interest,
regardless to where the vehicle or sight is pointing at.
This camera is controlled by the operator, and is aimed at
locations designated by the controller. Panoramic vision systems
are currently considered for installation in various combat
vehicles, including the MRAP.
