A MADRE ICBM Detection: Some Trajectory Parameter Determinations when Employing Ionospheric Refraction

Abstract

A Mercury-Atlas flight (AMR Test 1254) launched at 14:04:16Z, Sept. 9, 1961 was detected in the launch phase by the NRL Chesapeake Bay Annex Madre radar. The transmitter frequency was 13.7 Mc and its average power was 100 kw. The rotary antenna used had a gain of about 12 db. The type of signature obtained demonstrated the capability of an 'over-the-horizon' radar to measure range and range rate of the missile and its exhaust boundary. The characteristics of the signals detected suggest that information on target identification and trajectory can be extracted.
