    • A digital recording system for LORAN-C 

      Allan, Thomas D.; Montanari, Celsino (NATO. SACLANTCEN, 1967/04)
      A method for digitally recording the readings of a Collins LORAN-C Mk LR 101 Receiver on punched paper tape is described. The various advantages of automatically recording LORAN-C data are examined and it is shown how, ...
    • Accuracy of synthetic aperture sonar micronavigation using a displaced phase centre antenna 

      Pinto, Marc A.; Fioravanti, Stefano; Bovio, Edoardo (NATO. SACLANTCEN, 1999/02)
      This work evaluates the accuracy of multi-element synthetic aperture sonar (SAS) micronavigation based on the concept of displaced phase centre antenna (DPCA). The Cramér-Rao lower bound (CRLB) for the joint estimation of ...
    • Application of aided inertial navigation system to synthetic aperture sonar micronavigation 

      Tesei, Alessandra; Pinto, Marc A. (NATO. SACLANTCEN, 2001/01)
      In order to improve short-term navigational accuracy, critical to successful SAS processing, a highquality Inertial Navigation System (INS) is investigated, which consists of an inertial measurement unit (IMU) and a strapdown ...
