Direction of arrival (DOA) estimation for signals with large time‐bandwidth products is very
important in modern communication and radar systems. Traditional narrowband DOA …

Accurate direction of arrival (DOA) estimation of wideband, low-power nonstationary signals
is important in many radio frequency (RF) applications. This article analyses the …

In this paper, we propose a compressive sampling and reconstruction system based on the
shift-invariant space associated with the fractional Gabor transform. With this system, we aim …

The task of determining the coordinates of a radar station, in particular a low-flying target, is
to estimate the direction of arrival of an electromagnetic wave at the receiving antenna array …

This paper analyses the performance of two incoherent aggregation techniques for direction
of arrival (DOA) estimation of linear frequency modulated (LFM) radar signals. The aim is to …

Constant envelope OFDM (CE-OFDM) waveforms are increasingly being proposed for use
in terrestrial and satellite communications. The CE-OFDM technique phase modulates the …

This article studies the method of measuring cable length, using time-frequency domain
reflection method, and using linear frequency modulation signal at the signal injection end …

For underwater target detection, DOA estimation of wideband LFM sources is one of the
most important and challenging issues, which should be solved efficiently and reliably …

Wideband linear frequency modulation (LFM) signals are widely used in systems such as
radar, sonar and mobile. DOA estimation algorithms LFM signals rely on a large number of …
