In Radar applications, we are in need to identify the signals from the desired directions and to avoid unwanted signals from the enemies, which can be achieved by using the direction of arrival (DOA) estimation. Now-a-days we also meet the situation to use the power resources in an efficient manner by reducing the power allocation for inessential activities. In this paper, we consider these pro...

Multiple-Input Multiple-Output (MIMO) radar provides much more flexibility than the traditional radar thanks to its ability to realize far more observation channels than the actual number of transmit and receive (T/R) elements. In designing the MIMO imaging radar arrays, the commonly used virtual array theory generally assumes that all elements are on the same line. However, due to the physical...

Multiple-input Multiple-output (MIMO) radars benefit from spatial and waveform diversities to improve the performance potential. Phased array radars transmit scaled versions of a single waveform thereby limiting the transmit degrees of freedom to one. However MIMO radars transmit diverse waveforms from different transmit array elements thereby increasing the degrees of freedom to form flexible ...

Introduction With growth of applications such as beamforming, MIMO (multiple input multiple output) communications systems and even phase-array RADAR, the need for phase-coherent signal generation and acquisition systems is increasing. However, engineers still face challenges such as system size, cost and complexity. While you can use modular PXI instrumentation to solve many of the size and co...

i Abstract This thesis investigates the problem of target parameter estimation and performance analysis of multiple-input multiple-output (MIMO) radar in the presence of non-Gaussian clutter. During the past decades, multiple-input multiple-output (MIMO) radar has become a research subject of growing interest, due to its superior performance in many aspects over the traditional phased-array rad...

In modern electronic warfare, multiple input multiple output (MIMO) radar has become an important tool for electronic reconnaissance and intelligence transmission because of its anti-stealth, high resolution, low intercept and anti-destruction characteristics. As a common MIMO radar signal, discrete frequency coding waveform (DFCW) has a serious overlap of both time and frequency, so it cannot ...

One of the important obstacles in MIMO (Multiple Input Multiple Output) radars is the issue of designing proper transmit signals. Indeed, the capability of signal design is a significant advantage in MIMO radars, through which, the system can achieve much better performance. Many different aspects of this performance improvement have been considered yet, and the transmit signals have been desig...

this article deals with the issues associated with developing a new design methodology for the nonlinear model-predictive control (mpc) of a chemical plant. a combination of multiple neural networks is selected and used to model a nonlinear multi-input multi-output (mimo) process with time delays.  an optimization procedure for a neural mpc algorithm based on this model is then developed. the p...

Wideband Code Division Multiple Access (WCDMA) technology has emerged as the most widely adopted third generation (3G) air interface. 3GPP Release 7 (HSPA+) WCDMA systems introduced two features Higher Order Modulation (HOM) and Multiple Input Multiple Output (MIMO). MIMO improve the throughput in wireless medium. It achieves a higher spectral efficiency. This paper focuses on the performance a...
