Abstract : The object of the work performed was to develop a Radiosonde compatible with the operational electromagnetic environment of the Atlantic Missile Range. The presence of high-level radiation on adjacent frequencies make the standard AN/AMQ-9 unreliable in such an environment. Design objectives were (1) improved selectivity, (2) tuned frequency stability, (3) improved dynamic range, (4) reduced susceptibility to spurious responses and (5) provide five (5) channels with provisions for selection of one by changing one (1) component.
