This paper describes a method where a SAR system can be used with a single antenna both for transmitting and receiving. The system is using an antenna switch combined with a delayed version of the transmitted signal applied to the local oscillator of the detector.

Low-pixel-count imaging FMCW lidar
Applied Optics, 2022We demonstrate the imaging capability of a frequency modulated continuous wave (FMCW) lidar based on a fiber bundle. The lidar constructs velocity and range images for hard targets at a rate of 60 Hz. The sensing range is up to 30 m with 20 mW output power. The instrument employs custom electronics with seven parallel heterodyne receivers.

FMCW Implementation on LabVIEW
2018 International Conference on Computer and Applications (ICCA), 2018Thereare many possible system implementations for the Frequency Modulated Continuous Wave (FMCW) radar. In this paper, we will perform a full system level analysis for the implementation of the FMCW using LabVIEW communication. In the FMCW systems, the frequency is modulated at the source in order to measure the distance of the target and the velocity ...

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.

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.

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

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

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:

FMCW linearizer bandwidth requirements
Proceedings of the 1991 IEEE National Radar Conference, 2002The frequency-modulated continuous-wave (FMCW) linearity achievable as a function of the bandwidth of the linearizing frequency sweep modulator or linearizer is analyzed. This analysis pertains to millimeter-wave (MMW) radar seekers for short range air-to-ground missiles that employ the FMCW waveform because of weight, volume, and prime power ...
