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

Cascaded object detection networks for FMCW radars
Signal, Image and Video Processing, 2021Object detection using FMCW (Frequency-modulated continuous wave) radars is of massive importance for the advanced driver assistance systems. However, it is exceptionally challenging due to the diversity of the electromagnetic environment and the existence of the class imbalance in the radar data space.
