Abstract:

The ANMLQ-8XL-1 is a truck-mounted, swept-repeater jammer for predetonating artillery VT fuzes in the frequency band of 110 to 170 Mcs. Optimum operating parameters for the jammer were determined. The capability of the ANMLQ-8XL-1 to predetonate normal VT NVT fuzes of the T-226 type satisfactorily demonstrated at an extreme range of 15,000 yards for high-angle fire and 10,500 yards for low-angle fire, both under optimum conditions for the jammer including 90-degrees aspect. Use of the controlled CVT feature of the fuzes so that they arm 3 seconds before impact reduced the maximum ranges approximately 50. The jammer was tested under a number of adverse conditions which were found to reduce its effectiveness by from 20 to 90. From the results of the tests it was estimated that two jammers, properly sited and adjusted, placed 5,000 yards apart behind a substantially straight main line of resistance, can protect an area of about 6 square miles from CVT- and NVT-fuzed fire.
