Remote Interrogator for Munition Recorder Instrument Packages (RIMRIP)

ABSTRACT: Syntronics proposes the development of a shock hardened miniaturized Remote Interrogator which provides two way wireless communication through earth, water, and salt water. The range through these media is anticipated to be significantly greater than 5 meters at a data rate of 50kbits/sec or greater. Two technologies are used simultaneously. Ultra-sound is used for long range communication through water, and RF is used for long range communications through earth. The RF link is autonomously frequency agile in order to provide the maximum coupling with different soil types and moisture contents. BENEFIT: The development of the technology for a Remote Interrogator could be useful for through the earth communications for search and rescue in mines or underwater. The ruggedness, small size, and power consumption of the Remote Interrogator make this technology applicable as a location/communications device to be carried by an individual in danger of being trapped underground, water, ice, or snow, for example, a skier covered by an avalanche, a spelunker trapped in a cave, or a scuba diver trapped under water.
