Paper Abstract

The paper presents accuracy analyses of digital compression line which consists of digital quadrature detector, simple decimator and matched filter. Up to now analogue quadrature detectors are commonly used for many applications. These detectors suffer from bias and channel balance problems. However, the problem disappears while using digital solution. The main goal was to decrease the computation complexity needed for the processing without loosing the detection accuracy. It was achieved by using the class of digital quadrature detector with sampling frequency four times of IF frequency and simple phase correction filters.
