Adaptive time-compression stabilizer

摘要

Circuit for stabilizing the spectral extent of a varying signal containing harmonically related frequency components and having particular utility in the spectral analysis of radar return for the purpose of target identification. The variable signal is written into a storage device at a fixed rate and read out with a variable time compression which is controlled by a discriminator circuit that is connected through a filter to receive one of the harmonic frequency components of the storage device output signal. Also included is signal conversion for digital storage with analog input and output signals.
