Analysis of Environmental Assessment Procedures during OTH Emulator Test Flights

Abstract

HP propagation ionograms made between the OTH radar in Maine and the AFGL Airborne Ionospheric Observatory were analyzed. MOF values for the various modes identified were compared with MUF values derived from a quasi-mid-point ionospheric sounder (Argentia, Newfoundland). Discrepancies between MUFF1 and MOFF1 values were resolved by ray tracing through a realistic ionosphere (derived from the Argentia ionograms) and identified was due to difficulties in mode identification, when the E mode was dominant. The analysis shows that the MUF determination from mid-point vertical incidence ionograms provides acceptable frequency selection criteria for radar management.
