Digital array radar channel error analysis

The Journal of Engineering, 2019
The amplitude-phase error caused by the channel inconsistency in the actual digital array radar and the mutual coupling error caused by the mutual coupling effect have a great influence on the performance of the array.

Adaptive Gain Control Method of a Phase-Locked Loop for GNSS Carrier Signal Tracking

International Journal of Antennas and Propagation, 2018
The global navigation satellite system (GNSS) has been widely used in both military and civil fields. This study focuses on enhancing the carrier tracking ability of the phase-locked loop (PLL) in GNSS receivers for high-dynamic application. The PLL is a

All-optical signal processing of periodic signals using a Brillouin gain comb [PDF]

, 2008
The amplification of periodic signals using a Brillouin gain comb provides the opportunity to manipulate the amplitude and phase of a signal's individual spectral harmonics and, therefore, its temporal characteristics. In addition to obvious applications

An error tolerant, Ku-band, gain/phase control MMIC [PDF]

, 1992
A single chip, gain/phase control MMIC is described. The chip operates from 10.5 - 13GHz with 5 bit resolution and net gain. Numerical redundancy has been introduced to give tolerance to bit weight errors, the resulting advantage over a direct binary ...

Gain, phase imbalance, and phase noise effects on error vector magnitude

, 2004
The error vector magnitude (EVM) is extensively applied as a measure of communication systems' performance. In this paper, the effects of gain, phase imbalance, and phase noise on EVM are examined.
