A laser proximity sensor for a projectile includes a laser diode having front and rear facets. The diode generates a main laser signal and directs a first portion thereof out of the front facet as... Apr 01, 2002 · The ground crew selects a spin rate of up to 2500 rpm and sets the timer (up to 4.15 seconds) that opens the casing. For high-level release, an Alliant Techsystems FZU-39/B radar proximity fuze is preset to open the casing at heights of between 300 and 3000 feet. These two variants both had a dual fuze with impact and laser proximity sensors, with the proximity fuze able to be manually disabled prior to launch if the operator desired. BOLIDE has a selectable fuze with impact plus two proximity modes, the regular mode or a more sensitive small-target proximity mode for targeting drones and cruise missiles. Abstract: In order to improve the detection distance of laser proximity fuze without increasing laser power, the capability of laser fuze receiving weak laser echo signal must be improved. The fuze has a laser light source providing a beam directed onto the target via a lens (3), simultaneously used as the reception lens for a detector, for the laser light reflected from the target, with the detector output signal evaluated to determine the soiling of the lens. A laser proximity fuse was selected because RF fuses are vulnerable to EW intervention from enemy jammers. The increased diameter of ASRAAM also provides space for increased computing power, and so improved counter counter-measure capabilities compared with other dogfighting missiles such as AIM-9X.
