Radar/sonor spread spectrum high fidelity/precision demodulator having two double channel sets having test signals introduced and processing/amplifying, transposing then extracting test signal/removing errors.

摘要

The high fidelity and precision electrical signal demodultation spread spectrum system has two double sets of receivers. The output spectrums (R1(w) to R4(w)) are corrected for non linearities. The input signals (S(t)) and test signals (C(t)) are applied to summers (SOM1,SOM2). The signals are then amplified and transposed in four processing channels (RECk,CANk,FFTk) and passed to the correction unit, which separates the test signal from the useful signals and corrects the errors.
