Orthogonal waveforms for FMCW MIMO radar
2011 IEEE RadarCon (RADAR), 2011Multiple input/multiple output (MIMO) radar system performance benefits from the capability to simultaneously transmit and receive multiple orthogonal waveforms. For pulse radars fitting orthogonal waveforms have been developed. These waveforms are however not necessarily suitable for frequency-modulated continuous-wave (FMCW) radar.

Interference Characterization in FMCW radars
2020 IEEE Radar Conference (RadarConf20), 2020As the penetration levels of Automotive radars increase so will the problem of mutual interference. It is important to understand how this will affect the performance of current radar technology. The aim of this paper is the statistical characterization of interference in the context of fast chirp FMCW radar. We focus on two categories of interference:

Frequency Modulated Continuous Wave (FMCW) radars have been used by snow scientists for the past 30 years. This radar technology provides a promising alternative to point measurements, as properties such as snow depth can be measured quickly and non-destructively. Recent advances in microwave FMCW radar technology have resulted in lightweight, portable

Automated FMCW Radar Experimental Platform
2018 2nd IEEE Advanced Information Management,Communicates,Electronic and Automation Control Conference (IMCEC), 2018I258 the study of frequency modulated continuous wave (FMCW) radar, it is difficult to complete an experiment with application-specific radars, since adapting their parameters bring much cost and time-consuming work. To address this problem, this paper presents an efficient and automated FMCW radar experimental platform. As a control center, a computer

Pandora multifrequency FMCW/SFCW radar
Record of the IEEE 2000 International Radar Conference [Cat. No. 00CH37037], 2002This paper pertains to the design aspects of a multifrequency FMCW/SFCW radar with emphasis on the engineering problems involved in its implementation. The paper mostly discusses the FMCW mode of operation. This system can also be used for generating SFCW signals. The implications in this mode are also examined. In the FMCW mode, this radar generates 8

High resolution polarimetric FMCW radar
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002The Monash FMCW radar has been successful in detecting and locating defects in natural and man-made dielectrics (eg. defects in sawmill wood), with a range resolution, of 2 cm in wood. The authors show how to improve this resolution and provide polarimetric capability, which is important in anisotropic and optically active materials.

Frequency modulated continuous wave (FMCW) radar uses a very low probability of intercept waveform, which is also well suited to make good use of simple solid-state transmitters. FMCW is finding applications in such diverse fields as naval tactical navigation radars, smart ammunition sensors and automotive radars.

A 94GHz FMCW instrumentation radar
2007 Joint 32nd International Conference on Infrared and Millimeter Waves and the 15th International Conference on Terahertz Electronics, 2007We report on the use of a versatile 94GHz FMCW instrumentation radar to assess optimum hardware configurations for a variety of co-polar and cross-polar target classification studies. Phase noise and sweep linearity are critical parameters in FMCW radars and optimising them is a key objective of any high performance radar system.
