Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A method of operating a missile system having a laser illuminator for illuminating a target with laser beam and a guided missile with detector means capable of detecting reflected laser energy, and disposed for causing the missile to home on a target, the improvement comprising the steps of: discretely illuminating the target in a cluttered field of view with a collimated, coherent light beam of small cross sectional area with respect to the area of the target with laser illumination from the laser illuminator to provide reflection of said laser illumination from said target and in range of the guided missile; and homing the guided missile on said reflected laser illumination from the target for target interception and destruction.
Claim 2
Independent Claim
119 words
A method of operating a missile system having a laser illuminator for illuminating a target with laser beam and a guided missile with detector means capable of detecting reflected laser energy, and disposed for causing the missile to home on a target, the improvement comprising the steps of: discretely illuminating the target in a cluttered field of view with a collimated, coherent light beam of small cross sectional area with respect to the area of the target with laser illumination from the laser illuminator to provide reflection of said laser illumination from said target and in range of the guided missile; and homing the guided missile on said reflected laser illumination from the target for target interception and destruction.
Claim 3
Independent Claim
121 words
A method of operating a man portable missile system having a laser illuminator for illuminating a target with laser beam and a guided missile with detector means capable of detecting reflected laser energy, and disposed for causing the missile to home on a target, the improvement comprising the steps of: discretely illuminating the target in a cluttered field of view with a collimated, coherent light beam of small cross sectional area with respect to the area of the target with laser illumination from the laser illuminator to provide reflection of said laser illumination from said target and in range of the guided missile; and homing the guided missile on said reflected laser illumination from the target for target interception and destruction.
Claim 4
Independent Claim
121 words
A method of operating a man portable missile system having a laser illuminator for illuminating a target with laser beam and a guided missile with detector means capable of detecting reflected laser energy, and disposed for causing the missile to home on a target, the improvement comprising the steps of: discretely illuminating the target in a cluttered field of view with a collimated, coherent light beam of small cross sectional area with respect to the area of the target with laser illumination from the laser illuminator to provide reflection of said laser illumination from said target and in range of the guided missile; and homing the guided missile on said reflected laser illumination from the target for target interception and destruction.
Claim 5
Dependent Claim
16 words
The method as defined in claim 1 wherein said laser illumination energy is infrared wavelength energy.
Claim 6
Dependent Claim
16 words
The method as defined in claim 2 wherein said laser illumination energy is infrared wavelength energy.
Claim 7
Independent Claim
100 words
A method of operating a guided missile for intercepting a target in a cluttered field of view comprising the steps of: discretely illuminating a target in a cluttered field of view with laser illumination of small cross sectional area with respect to the area of the target; detecting reflected laser illumination from the target, and homing the guided missile when within range of said reflected laser illumination with detector within the missile that is capable of detecting said reflected laser illumination to cause guidance of the missile to thereby home on the target and intercept the target for destruction thereof.
Claim 8
Independent Claim
100 words
A method of operating a guided missile for intercepting a target in a cluttered field of view comprising the steps of: discretely illuminating a target in a cluttered field of view with laser illumination of small cross sectional area with respect to the area of the target; detecting reflected laser illumination from the target, and homing the guided missile when within range of said reflected laser illumination with detector within the missile that is capable of detecting said reflected laser illumination to cause guidance of the missile to thereby home on the target and intercept the target for destruction thereof.
