A Determination of the Wideband Modulation Capabilities of Jamming Transmitter AN/ALT-2,

Abstract

In the interest of developing improved jamming effectiveness in the current modifications to the AN/ALT- 2 transmitter portion of the AN/ALQ-23 automatic search and jam system, an analysis was made of the modulation capabilities of its X-band unit. Test data supplied by makers of the component magnetrons, indicated that noise modulation components out to 10 Mc could not be reproduced in the X-band magnetron output under present equipment limitations. It now appears that the manufacturers' test data were affected by certain modifying conditions, since studies indicate no inherent limitations within the tubes to prevent reproduction of video modulation components up to at least 10 Mc.
