Portable surface-to-air missile system

Abstract

A portable surface-to-air missile system has a missile with a frequency-modulated infrared autonomous guidance head and a selector electrically and pneumatically connected to a launcher, said selector being formed as an infrared autonomous guidance head operable to use kinematic differences between a real target and a deception flare, and said launcher having an indicator changing an operating program of said selector.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a missile technology and particularly to portable surface-to-air missile systems (PSAMs). [0002] Portable surface-to-missile systems are known, which have been designed to hit targets moving at low altitudes, as disclosed for example in the international patent application WO 98 / 16794 published on Apr. 23, 1998. The known portable surface-to-air missile system includes a guided missile with an optical autonomous guidance head and a launcher connected to it, which includes a transport-and-launch container, a power supply unit, and a device increasing the precision of hitting. However, the known system does not insure separation of deception targets from real ones and therefore its efficiency is low. [0003] Another known solution is disclosed in U.S. Pat. No. 6,565,036 published on May 20, 2003 which claims an enhanced precision of hitting of high-speed air targets. However, this system is mainly designed for artiller...

AI Technical Summary

Benefits of technology

[0008] It is therefore an object of the present invention to provide a portable surface-to-air missile system, in which vulnerability to flares is minimized by equipping autonomous guidance head of the system with a system distinguishing the target from an IRDF.

Problems solved by technology

However, the known system does not insure separation of deception targets from real ones and therefore its efficiency is low.

In addition, both the placement of light sensors inside such a rod and the use of optical lens substantially complicate this known system.

This substantially complicates both the missile design (Kalman filters need to be installed) and its launch.

In addition, it requires additional substantial expenses.

The main disadvantage of this known solution is a not sufficiently high flare resistance of the surface-to-air missile system, whereas the anti-flare requirements are among the decisive ones.

At a time the target that has aimed at and the IRDF do not fit into the sight of the missile guiding system, and since the guidance system is tracking a more powerful IRDF, the target that has been aimed at goes out of the missile guidance system, which results in missing it.
