AbstractNot Available Effectiveness of weapons designed to inflict damages to underground targets cannot be assessed in real time without a data link between the penetrating body and a receiver on the surface. To implement a radio link, the radio transmitter output power must be sufficiently large to overcome the signal absorption in the ground. The radio signal absorption in the ground has been studied in the past, and a preliminary data base has been established. For direct assessment of penetrating weapons, however, a transmitter designed specifically for this application is desired. This proposal describes an approach to design and demonstrate a transmitter suitable for applications in penetrating weapons. Problems and issues unique to this application include: G-hardening and frequency stability during the penetration phase, frequency selection for optimum signal transmission, and the power output estimated to acquire and maintain a link. The proposed approach is to design a single transmitter signal source into a single chip and combine it with a power amplifier operating at output levels of 100 watts or more. The preferred frequency of what operation is in the VHF ban of 225-300 MHz. The operating scenario assumes that there will be an airborne receiver in a relay station deployed near the penetrating point. The signal loss from the transmitter to the receiver is expected to be of 140dB. A directive antenna conformal to the penetrating body is assumed for the transmitter. The propose
