Methods of Compensation for the Automatic Frequency Control Loop (AFC) and Automatic Phase Control Loop (APC) in the MAULER Receiver.

Abstract

The forms of compensation in the AFC and APC loops for the Mauler receiver are discussed. Basic compensation considered for both AFC and APC loops are first order lag-lead networks. Effects of loop gains and corner frequencies of the compensation networks are considered parametrically. The study is divided into three parts: (1) linearized system response to a ramp change in doppler frequency without time delay, (2) system response to a ramp change in doppler frequency, (3) loop stability analysis. Responses for (1) were computed on the digital computer. Responses computed for (2) utilized an analog computer simulation which included the non-linearity in the phase detector. The analysis under (3) includes effects of pure time delays in the IF amplifier and the discriminator.
