2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Frequency modulated continuous wave (FMCW) radar, optionally with Doppler capability, is applied in atmospheric remote sensing since decades. The method is well understood and documented in its original theoretical analogue representation, as are its inherent restrictions. But since the introduction of the method the digitization has reached many areas

A coverage efficient FMCW positioning system
2016 International Conference on Localization and GNSS (ICL-GNSS), 2016Accurate positioning with a limited number of reference stations is challenging. Several commercial systems achieve good accuracy by increasing the system complexity. Simplifying the system and reducing the number of reference stations is highly desirable. This paper presents a coverage efficient highly integrated local positioning system.

Performance of an FMCW radar sensor
IEEE Transactions on Communications, 1992An FMCW (frequency modulated continuous wave) sensor that uses triangular modulation is considered. The sampled output from two range gates are processed so that the device will initiate some function when it passes through a desired range. An expression is obtained for the detection probability from which the expected value and standard deviation of ...

FMCW system aspects for multipath environments
2011 8th Workshop on Positioning, Navigation and Communication, 2011Local positioning systems (LPS) are not only of increasing interest for industrial and commercial applications, but are also required for crisis management to keep track of first responders at all times, both for security and for logistic reasons. In such systems, frequency-modulated continuous wave (FMCW) radar is widely used.

An FMCW Ranging Method with Identification Ability
2019 IEEE International Workshop on Signal Processing Systems (SiPS), 2019Frequency modulated continuous wave (FMCW) radar has been widely used and thoroughly studied in high precision ranging. However, FMCW radar cannot identify target type while ranging. To address this problem, this paper presents a high-precision ranging method based on FMCW, which enables the FMCW radar to identify target type while ranging.

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:

IEE Proceedings, Part F: Radar and Signal Processing, 1992
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.

TIA Design for FMCW LiDAR Systems
International Journal of Circuit Theory and ApplicationsABSTRACTThis paper presents a design methodology for a transimpedance amplifier (TIA) that emphasizes enhanced power supply rejection ratio (PSRR), specifically tailored for long‐distance frequency‐modulated continuous‐wave (FMCW) LiDAR systems. In these advanced systems, when critical components such as the transmitter, receiver, and optical phase ...
