FMCW lidar for autonomous vehicles
High-Power Diode Laser Technology XIX, 2021Aurora’s automotive frequency-modulated continuous-wave (FMCW) lidar technology has been designed and developed to address the needs of level 4/5 autonomous vehicles (AVs). Aurora’s FirstLight provides eye-safe and long-range performance, radial velocity on every point, and high spatial density.

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:

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.

Cold Regions Science and Technology, 2008
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

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.

Design of a Multifrequency FMCW Radar
28th European Microwave Conference, 1998, 1998This paper pertains to the design aspects of a multifrequency FMCW radar with emphasis on the engineerig problems involved in its implementation. This radar generates 8 separate FMCW signals which are then additively mixed and radiated. The target return also comprises returns at these frequencies. The signals are then split into their constituents and
