Radar echo analysis

TL;DR: In this paper, the authors present a radar detection and signal processing circuit where, following a front end having an RF and local oscillator mixer to an I.F., which is then further mixed against a signal from a swept frequency oscillator, the output of a band pass filter goes to a detector for frequency modulated intermediate frequency signals, and that detector has at least a first output signal that is fed to two pairs of complementary paired comparators, the outputs of which are set to low and high threshold levels.

TL;DR: The acceleration compensation technique described in this radar generates matched filters that compensate for each acceleration, which provides direct and precise measurement of target acceleration for enhanced detection and tracking of maneuvering targets.
