–To locate snipers in urban environments.
–Work with constraints of the urban environment
•Multipath effects
•Poor coverage due to shading effect of buildings
–Limitations of existing systems
•Require direct line of sight
•Rely on muzzle flash that can be suppressed •Centralized system not tolerant to sensor failure
–Cost effectiveness.
–Slide 4
–Use an ad-hoc wireless sensor network-based system
–Utilize many cheap sensors for
•good coverage of direct signal
•tolerance to failures
–Detect via acoustic signals like muzzle blasts and shockwaves
