Research Institution
Objective of the proposed research effort is to design, build and test an experimental AJ antenna for GPS receiver and Iridium transceiver functionality and to develop novel signal processing techniques without compromising the AJ suppression capability of either of the two systems. The AJ antenna will have at least four elements and will be approximately four inch in diameter. The individual antenna elements will be designed to receive M-coded GPS signals in L1 and L2 band as well as receive and transmit Iridium communication system signals simultaneously. Since the transmitted signal is much stronger than the received signals, the antenna must provide good isolation to enable the simultaneous reception of weak navigation and communication signals and transmission of strong communication signal. In this project, Applied EM along with its team members will develop a new signal processing algorithm for the antenna electronics (AE) such that the signal processing capability of a given receiver (GPS or Iridium) are not compromised by the presence of the other signals. Size, weight and Power (SWAP) will be considered in the development of antenna and antenna electronics so that the same antenna system can be used for airborne as well as undersea vehicles.
