Abstract : A comprehensive set of tests performed on the USMC High Frequency SSL System was carried out at SURC in two phases. The Phase I tests, concerned with equipment response and effects, disclosed various system discrepancies such as significant pre-amp impedance mismatch. These discrepancies were then corrected and Phase II tests, concerned with effects on system performance due to antenna configuration, were carried out. The incorporation of improved signal processing to the results of these tests enabled the system to operate within predicted performance. (Author)
