  • Low-drag, ram-air inflated, millimeter wave, passive radar decoy
    Patent number: 4709235
    Abstract: An aircraft-launched, ram-air inflatable, passive radar decoy (10) has a substantially cylindrically shaped body (12) having an open forward end (14) and a closed porous rearward end (16), the body comprised of a fabric reinforced composite having a high radar reflectivity coating on at least it interior surfaces (12i, 16i). A rod-shaped weight (22) is attached at the forward end (14) by way of shroud lines (20), the weight (22) providing the highest weight-to-drag-area ratio for the particular size body. The decoy (10) provides a high radar cross section and broad angle coverage to ground-based source of radar when it is ram-air inflated upon ejection by the aircraft into its adjacent windstream.
