Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 132 words
A rolling vehicle seeker system comprising: (a) first receptor means mounted upon the rolling vehicle to receive energy in a first spectral range of radiation from a prospective target and produce a first output signal; (b) second receptor means mounted upon the rolling vehicle to receive energy in a second spectral range of radiation from the same prospective target and produce a second output signal; and (c) signal processing means operably associated with said first and said second receptor means to receive said first and said second output signals therefrom to produce a first error signal from said first output signal and a second error signal from said second output signal and including means to continuously select between said first error signal and said second error signal according to a preselected logic.
Claim 2
Dependent Claim 132 words
A rolling vehicle seeker system comprising: (a) first receptor means mounted upon the rolling vehicle to receive energy in a first spectral range of radiation from a prospective target and produce a first output signal; (b) second receptor means mounted upon the rolling vehicle to receive energy in a second spectral range of radiation from the same prospective target and produce a second output signal; and (c) signal processing means operably associated with said first and said second receptor means to receive said first and said second output signals therefrom to produce a first error signal from said first output signal and a second error signal from said second output signal and including means to continuously select between said first error signal and said second error signal according to a preselected logic.
Claim 3
Dependent Claim 30 words
The rolling vehicle seeker system of claim 1 wherein said signal processing means additionally includes means to continuously update the error signal not selected by the error signal selection means.
Claim 4
Dependent Claim 25 words
The rolling vehicle seeker system of claim 2 wherein said error signal updating means utilizes the selected error signal to update the non-selected error signal.
Claim 5
Dependent Claim 21 words
The rolling vehicle seeker system of claim 2 wherein said non-selected error signal updating means includes at least one feedback path.
Claim 6
Dependent Claim 26 words
The rolling vehicle seeker system of claim 2 wherein said error signal updating means includes a feedback path shared by the selected and non-selected error signals.
Claim 7
Dependent Claim 41 words
The rolling vehicle seeker system of claim 1 wherein: (a) said first receptor means is active to receive radiation reflected from a prospective target and (b) said second receptor means is passive to receive radiation emanating from the same prospective target.
Claim 8
Dependent Claim 44 words
The rolling vehicle seeker system of claim 6 wherein: (a) said active first receptor means comprises at least two antennas to receive reflected electromagnetic radiation; and (b) said passive second receptor means comprises seeker means to receive infrared radiation emanating from the prospective target.
Claim 9
Dependent Claim 257 words
The rolling vehicle seeker system of claim 1 wherein said first receptor means includes: (a) a first antenna operably mounted upon the rolling vehicle to receive said energy in said first spectral range of radiation from the prospective target; and (b) a second antenna operably mounted upon the rolling vehicle to also receive said energy in said first spectral range of radiation from the prospective target; and wherein said signal processing means includes: (c) first microwave mixer means operably connected to said first antenna to receive said first output signal; (d) second microwave mixer means operably connected to said second antenna to also receive said first output signal; (e) phase shift network means including a phase shifter operably connected to said first microwave mixer means to shift the phase of said first output signal in said first microwave mixer means; (f) an oscillator operably connected to said phase shifter and to said second microwave mixer means; (g) a phase comparator operably connected to said first and second microwave mixer means and responsive thereto; (h) an RF signal processor of said error signal selection means operably coupled to said phase comparator and responsive thereto; (i) a modulator operably connected to said RF signal processor and responsive thereto, said modulator additionally being operably coupled to said error signal selection means and to said phase shift network means; and (j) circuit means operably connected to said error signal selection means and to said phase shift network means for receiving and processing said selected error signals to control the rolling vehicle.
Claim 10
Dependent Claim 83 words
The rolling vehicle seeker system of claim 1 wherein said error signal selection means includes: (a) a switch; (b) error signal selector means operably coupled to said switch to control said switch; (c) first signal processor means operably connected to said error signal selector means for providing said first error signal to said error signal selector means; and (d) second signal processor means operably connected to said error signal selector means for providing said second error signal to said error signal selector means.
Claim 11
Dependent Claim 39 words
The rolling vehicle seeker system of claim 8 wherein said circuit means comprises: (a) an amplifier operably connected to said error signal selection means and responsive thereto; and (b) a demodulator operably connected to said amplifier and responsive thereto.
