Aerial drop telemetering sensor

Abstract

Abstract PRELIMINARY SEISMIC EXPLORATION AND EXPLORATION IN REMOTE ACCESS AREAS MAY BE CARRIED OUT WITH A LOW-COST, EXPENDABLE SEISMIC TELEMETERING UNIT CONTAINED IN A TWOPART AIR-DROPPABLE PROBE THAT INCLUDES AN UPPER SECTION (LIGHT MASS) DESIGNED TO REMAIN AT THE SURFACE AND A LOWER SECTION (HEAVE MASS) THAT IS BURIED TO A DEPTH DEPENDING UPON THE SOIL CONDITIONS. AS THE TWO-PART PROBE EMBEDS ITSELF IN AN EARTH-LIKE SURFACE, IT GENERATES UNDERGROUND SEISMIC WAVES, THEREBY ACTING AS ITS OWN SOURCE OF SEISMIC ENERGY. MANY PROBES MAY BE DROPPED IN AN EXPLORATION AREA IN ANY DESIRED SPREAD TO PRODUCE THE DESIRED SEISMIC DATA. THE IMPACT OF EACH PROBE GENERATES A NEW SET OF ENERGY WAVES THAT WILL BE PICKED UP BY ALL EARLIER DROPPED PROBES. BY APPROPRIATE CODING OF THE TRANSMITTED ENERGY, AN AIRBORNE COMPUTER WILL SEGREGATE THE SIGNALS FROM EACH PROBE TO PRODUCE SEISMIC DATA THAT MAY BE READ IN THE USUAL MANER. SEISMIC WAVES ARE DETECTED BY A SEISMIC SENSOR IN THE LOWER SECTION (SENSOR SECTION) WHICH GENERATES ELECTRICAL SINALS PROPORTIONAL TO TE TRAVELING WAVES. THESE ELECTRICAL SIGNALS ARE AMPLIFIED BY ONE OF MANY DIFFERENT AMPLIFICATION SYSTEMS, DEPENDING OF THE APPLICATION, AND CONVERTED INTO RADIO FREQUENCY SIGNALS IN A RADIO TRANSMITTER. AN ANTENNA IS MOUNTED TO EXTEND ABOVE THE EARTH''S SURFACE AS A COMMUNICATION LINK BETEEN THE RADIO TRANSMITTER AND A RADIO RECEIVER OPERATING AT A REMOTE LOCATION.
