  • Tracking radar receiver
    Patent number: 6486824
    Abstract: A tracking radar receiver as described herein is relatively invulnerable to image frequency jamming. Partial image-rejection down-converters down-convert RF signals to IF signals in each of various sum and difference receiver channels. Image frequency components of the IF signals exhibit a predetermined amplitude and phase relationship relative to corresponding real frequency components for each of the channels. Thus, phase and amplitude tracking between the various channels is achieved even when image frequency signals are received.

  • Radar range tracking apparatus and method
    Patent number: 4587523
    Abstract: A split gate, leading edge range tracking apparatus for use in coherent radar seekers is substantially balanced in noise. The early and late gate widths and channel gains are chosen to provide leading edge tracking while avoiding range drift during target fade. A relationship is derived whereby the ratio of the early and late gate widths equals the square root of the ratio of the late and early gate channel gains.

  • Random voltage source with substantially uniform distribution
    Patent number: 4578649
    Abstract: A Gaussian noise generator having a sample and hold circuit connected to the output thereof for providing random voltage samples, a voltage controlled oscillator controlled by the random voltage samples and providing a linear 10 sawtooth output having a frequency dependent upon the amplitude of the random voltage samples, and a second sample and hold circuit connected to the oscillator to provide random voltage output samples with substantially uniform distribution between predetermined limits.
