Radiometric absolute noise-temperature measurement system features improved accuracy and calibration ease
Radiometric receiver system, which measures noise temperatures in degrees Kelvin, does not require cryogenic noise sources for routine operation. It eliminates radiometer calibration errors associated with RF attenuation measurements. Calibrated noise source is required only for laboratory adjustment and calibration.

High-accuracy detector for laser radar
Signal processing technique permits accurate timing of pulse position independent of pulse amplitude. Technique utilizes differentiator, limiter amplifier, Schmitt trigger, and monostable multivibrator to produce standard-width pulse whose leading edge corresponds with the maximum of the received signal. This pulse stops the range counter.
