Objective of Phase Effort
The main goal of the Phase I project wad to design and build a breadboard prototype of a temporary personnel incapacitation system called MEDUSA (Mob Excess Deterrent Using Silent Audio). This non-lethal weapon is based on the well established microwave auditory effect (MAE). MAE results in a strong sound sensation in the human head when it is irradiated with specifically selected microwave pulses of low energy. Through the combination of pulse parameters and pulse power, it is possible to raise the auditory sensation to the discomfort level, deterring personnel from entering a protected perimeter or, if necessary, temporarily incapacitating particular individuals.
Summary of Results from the Phase I Effort
The major results of the Phase I effort were that - An operating frequency was chosen - Hardware requirements were established (commercial magnetron, high-voltage pulse former) - Hardware was designed and built - Power measurements were taken and the required pulse parameters confirmed - Experimental evidence of MAE was observed
Potential Applications and Benefits
Potential applications of the MEDUSA system are as a perimeter protection sensor in deterrence systems for industrial and national sites, for use in systems to assist communication with hearing impaired persons, use by law enforcement and military personnel for crowd control and asset protection. The system will: be portable, require low power, have a controllable radius of coverage, be able to switch from crowd to individual coverage, cause a temporarily incapacitating effect, have a low probability of fatality or permanent injury, cause no damage to property, and have a low probability of affecting friendly personnel. http://www.navysbirprogram.com/NavySearch/Summary/summary.aspx?pk=F5B07D68-1B19-4235-B140-950CE2E19D08
