Description of original award (Fiscal Year 2004, $499,995)

Raytheon proposes to develop an innovative portable less-lethal system, which effectively repels personnel with less collateral damage than existing systems, by implementing solid state RF technology in a directed energy system and demonstrating a prototype of that system.


These funds to Raytheon Corporation are for the continued research in developing a LL Device using RF Technology. This continuation will be used to design a solid state 95GHz oscillator to feed the solid state amplifier previously funded. ca/ncf

This award is for Raytheon to build and deliver a battery powered solid state (SS) radio frequency (RF) directed energy (DE) less-than-lethal table-top demonstrator unit. The unit produces a small beam of less-than-lethal RF directed energy output for a short duration, enabling demonstration of this type of energy on a small scale with greater standoff range then the previous solid state demonstrator finger machine. It allows justice, law enforcement and corrections officers to evaluate the efficacy of this type of system for less-than-lethal applications and envision the implementation of a practical device based on many of this unit's design characteristics.

This project will build a solid state (SS) radio frequency (RF) directed energy (DE) less-than-lethal man-portable device brassboard. This project is designed to develop a new tool and technology for use by local law enforcement agencies. The unit will produce a beam of less-than-lethal RF directed energy output for a significant duration and range, enabling the full demonstration of the capabilities of a man-portable active denial device. RF energy at this frequency will only penetrate a small fraction of the skin, just enough to excite an individual's nerve endings. This will cause the target to feel intolerable discomfort and cause the individual to change their behavior. This device is designed to not cause permanent injury.

This device brassboard will allow law enforcement, corrections officers, military, etc. to evaluate the capability and usefulness of this type of system for less-than-lethal applications and to provide suggestions on how to make a fielded production version of the device better. This device will allow law enforcement practitioners to affect the behavior of individuals from a stand off distance with a minimal chance of injury to the practitioner, target, or bystanders. nca/ncf
