Radar 2020: The future of radar systems

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
The first radar was patented 110 years ago. Fast forward to today, radar applications have become ubiquitous in typical applications i.e. speed control, air traffic control, airborne and space-borne missions, military applications and remote sensing. Research for medical radar applications is also progressing well for breast cancer detection and tumor ...

MIMO radar, SIMO radar, and IFIR radar: a comparison

2009 Conference Record of the Forty-Third Asilomar Conference on Signals, Systems and Computers, 2009
This paper focuses on a simple beamforming problem and compares the MIMO and SIMO radar systems for the case where the transmitter and receiver are collocated. The simplicity of the application allows one to see clearly where the advantages of MIMO radar come from, and what the tradeoffs are.

RADAR | Precipitation Radar

2003
Precipitation radars scan their vicinity to determine the location, intensity, and structure of showers and storms. Several different radar variables are used to determine different aspects of the precipitation. Radar reflectivity measures the number and size of particles. In radars that transmit and receive horizontally as well as vertically polarized

Metacognition in radar

2010 2nd International Workshop on Cognitive Information Processing, 2010
An airborne ground looking radar sensor's performance may be enhanced by selecting algorithms adaptively as the environment changes. A short description of an airborne intelligent radar system (AIRS) is presented with an in-depth description of the knowledge based filter and detection portions.

The rolling radar

IEEE International Radar Conference, 2005., 2005
In the search for a better rotating radar, a self-supporting array that rolls like a wheel can improve mechanical reliability and return higher-definition target resolution. The Rolling Radar concept evolved from the need to design and build a large rotating 3D radar as an alternative to multifaceted fixed radar installations, or large, expensive ...
