Maximum likelihood (ML) direction-of-arrival (DOA) estimation is essentially an optimization
of multivariable nonlinear cost function. Since the final estimate is highly dependent on the …

The effect of bias current variation in the dynamics of a conventional BJT based Colpitts
Oscillator (CO) has been thoroughly examined in this paper. After formulating a suitable ac …

Antenna element and array with harmonic suppression ability are desired in compact and
integrated RF front-end systems, because they can lead to remove the additional bandpass …

There is no doubt that chaotic systems are still attractive issues in various radar applications
and communication systems. In this paper, we present a new 0.3 GHz mono-static …

In this paper, a novel low phase noise voltage-controlled oscillator (VCO) using
metamaterial structure and rat race coupler is presented for reducing the phase noise …

In this paper, an analysis of radar range and probability of detection by the use of multiple-
input multiple-output (MIMO) radar with cooperative high altitude aeronautical platforms …

Radar is a detection system that uses radio waves and depends on many parameters. The
waveform of the transmitting signal represents an important factor in the detection …

In this paper, we propose a new method of measuring the target velocity by estimating the
scaling parameter of a chaos-generating system. First, we derive the relation between the …
