Multiple-input multiple-output (MIMO) radar: performance issues

Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005
The application of multiple-input multiple-output (MIMO) techniques to multistage radar offers a number of advantages, including improved resolution and sensitivity. Depending upon the radar's mode of operation, the array design and the environment, these advantages may or may not be significant. In this paper, a simple analytic model for ground moving

Multiple-input multiple-output (MIMO) radar and imaging: degrees of freedom and resolution

The Thrity-Seventh Asilomar Conference on Signals, Systems & Computers, 2003, 2004
In this paper, radar is discussed in the context of a multiple-input multiple-output (MIMO) system model. A comparison is made between MIMO wireless communication and MIMO radar. Examples are given showing that many traditional radar approaches can be interpreted within a MIMO context. Furthermore, exploiting this MIMO perspective, useful extensions to

On the detectability of multiple input multiple output (MIMO) radar signals using conventional Electronic warfare support (ES) receivers

2015 IEEE Radar Conference, 2015
Multiple-Input Multiple-Output (MIMO) radar is a more general form of phased array radar, where each antenna in the array transmits mutually linearly independent or orthogonal signals. Modern day growth in computational power has made MIMO more viable than in the past.

Improvement of Doppler measurement using multiple-input multiple-output (MIMO) concept in radar-based automotive sensor detecting pedestrians

Sensor Review, 2018
Purpose This paper aims to present an approach of utilizing multiple-input multiple-output (MIMO) radar concept to enhance pedestrian classification in automotive sensors. In a practical environment, radar signals reflected from pedestrians and slow-moving vehicles are similar in terms of reflecting angle and Doppler returns, inducing difficulty for ...

Initial surface current measurements on the West Florida shelf using WERA HF ocean radar with multiple input multiple output (MIMO) synthetic aperture

2014 Oceans - St. John's, 2014
High-frequency (HF) radar systems located at the coast are well-known as a measurement tool for synoptic online mapping of ocean surface current fields. These radars use surface electromagnetic wave propagation coupled to the salty ocean surface and are capable of monitoring thousands of square kilometers of the ocean surface.

Three-dimensional through-the-wall imaging with multiple-input multiple-output (MIMO) radar

Journal of Electromagnetic Waves and Applications, 2014
One of the main drawbacks of three-dimensional (3-D) through-the-wall imaging (TWI) with synthetic aperture radar is the long data acquisition time. The movement of the target during the long data collection time in TWI causes smearing and target displacement in the image.

Novel approaches for target parameter extraction with eigenvalue thresholding and Dolph–Chebyshev windowing in multiple‐input multiple‐output (MIMO) radar system

International Journal of Communication Systems
SummaryMultiple‐input multiple‐output (MIMO) radar, employing multiple transmitters and receivers, enhances radar capabilities. It detects and tracks objects like aircraft and ships using radio waves. Compared with traditional phased‐array radar, MIMO systems offer greater flexibility, improving angular resolution and target detection.
