Phased-multiple-input multiple-output (phased-MIMO) radar using one-dimensional transmit arrays has been thoroughly investigated in the literature. In this paper, we consider two-dimensional phased-MIMO radar array which is called planar-phased-MIMO radar. This new technique aggregates the advantages of the linear-phased-MIMO radar without sacrificing either the main advantage of the planar-pha...

Abstract: The MIMO phased array radar is a theoretical concept for multi-sensor radar planning that combines elements of traditional phased-array radar with the developing technology of multiple-input multiple output (MIMO) radar. Space-time coding (STC) has been shown to play a key role in the design of Phased Array MIMO radar where MIMO radar can achieve improved localization performance by ...

APhased MIMO radar with full waveform diversity is proposed which divides the transmit array into overlapping subarrays in such a way that the number of subarrays are equal to the number of transmit antennas. Each subarray send sout a unique wave form towards the target of interest and thus provides a full waveform diversity, which results in the virtual extension of received array. This virtua...

In this paper, we focus on target detection and system configuration optimization of Multiple-input Multiple-output (MIMO) radar in low-grazing angle, where the multipath effects are very abundant. The performance of detection can be improved via utilizing the multipath echoes. First, the reflection coefficient, considering the curved earth effect, is derived. Then, the general signal model for...

We recommend a novel method for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The core of the projected method is to panel the broadcast array into a number of sub arrays that are permissible to overlie. Then, each subarray is worn to articulately put on the air a waveform which is orthogonal to the waveforms transmitted by additional subar...

In this paper, the problem of target detection in phased-MIMO radars is considered and target detection performance of phased-MIMO radars is compared with MIMO and phased-array radars. Phased-MIMO radars combine advantages of the MIMO and phased-array radars. In these radars, the transmit array will be partitioned into a number of subarrays that are allowed to overlap and each subarray transmit...

A MIMO (multi-input multi-output) radar system, unlike a standard phased-array radar, can transmit via its antennas multiple probing signals that may be correlated or uncorrelated with each other. We provide herein an overview of our recent result, showing that this waveform diversity enables the MIMO radar superiority in several fundamental aspects, including: 1) significantly improved paramet...

Abstract—Multiple-input multiple-output (MIMO) radar has received increasing attention in recent years. MIMO radar has many advantages over conventional phased array radar such as target detection,resolution enhancement, and interference suppression. In this paper, the results are presented from a simulation study of MIMO uniformly-spaced linear array (ULA) antennas. The performance is investig...

Multiple input multiple output radars transmit partially coherent or noncoherent waveforms for improving spatial resolution or spatial diversity. While waveform design for SIMO radars concentrate on improving the delay and Doppler resolution characteristics, waveform design for MIMO radars involve optimization of delay, Doppler and spatial resolution characteristics. The resolution properties o...
