In an attempt to determine the feasibility of OTH detection of ABM devices the Naval Research Laboratory commenced observations in July 1967, of Sprint missile launches from the White Sands Missile Range. For these tests the NRL backscatter radar was deployed in a coherent pulsed mode with transmitter power above 1MW peak on radio frequencies near and above 20MHz. Of 10 tests monitored 8 have yielded detected signals that seem related to the launch event. System insensitivity in one instance and launch abort in the other precluded significant results on the other two tests.
