Abstract
This paper describes the linear FM ramp generator that provides the wideband transmitted signal and correlation receiver reference for the long-term imaging RADAR (LRIR) developed and operated by the M.I.T. Lincoln Laboratory. The signal generated has a bandwidth of 1000 MHz and a duration of 250 mu s. Because of its large time-bandwidth product, the signal is generated actively by sweeping a voltage-controlled oscillator. Special attention is given to the means for achieving linearity, reproducibility, and coherence of the generated ramps.
