ABSTRACT:
A closed loop frequency control system for maintaining accurate linearity in the transmitted signal (60) in a linear frequency modulated (LFM) chirped laser radar system. A correction signal (50), derived from an output pulse monitor is summed with the modulation waveform (18) to correct non-linearities in real time.
