A second generation FM-CW radar sounder is described which has scanning capability and is fully mobile. The sounder is used as a remote sensor with unprecedented range resolution for fine scale structural details in the lower troposphere. Design considerations and performance characteristics of this new sounder are presented and examples of ...

This paper describes a radar system in which a measure of range is obtained as the phase difference between amplitude modulations on the transmitter and echo signals. Significant features of this AM radar system are simplicity and capability of accurately measuring very short ranges.

On radar polarimetry in FM-CW radar
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002This paper attempts to apply the principle of radar polarimetry to wideband synthetic aperture FM-CW radar and presents a basic polarimetric detection result of a linear target in a laboratory measurement. Although the principle of radar polarimetry has well been established for the completely polarized wave and for the monostatic case, it still needs ...

Approaching/Receding Target Detection using CW Radar
2020 5th International Conference on Communication and Electronics Systems (ICCES), 2020In this work, a new frequency shifting technique is proposed. Using this technique, direction (Approaching/Receding) of the target can be determined using a continuous wave (CW) Radar system. In general, in the classical technique, a huge complex computation is required to find the direction of the target using CWR radar which motivated us to develop a

Towards a Full-Duplex CW Radar
Proceedings of the 6th International Conference on Telecommunications and Remote Sensing, 2017This paper deals with the challenges of transmitter-receiver isolation in Continuous-Wave Radars. Based on a Full-Duplex configuration, the leakage power from typical modern radar components has been measured. The aim of this study is the suppression of this self-interference in the digital domain.

Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002
The objective of the described CW radar resulted from the threat by anti-radiation-missiles. Instead of a scanning transmit beam with high gain an antenna with a broad illumination pattern is used. Therefore the radiation may be covered by a decoy transmitter all the time. The transmitted CW-signal is modulated by a polyphase code for range resolution.

Advanced polarimetric subsurface FM-CW radar
IEEE Transactions on Geoscience and Remote Sensing, 1998The subsurface radar suffers from two typical problems, i.e., strong clutter from surface and severe wave attenuation in the underground. This paper presents a unique countermeasure to these problems using a polarimetric FM-CW radar and an equivalent sensitivity time control (STC) technique.

Proceedings of the IEEE, 1972
Raven has analyzed the CW radar output assuming a low-level sinusoidal phase disturbance. The radar output is herein analyzed for arbitrary amplitude sinusoidal phase disturbance. Also, the output amplitude spectrum is shown to be related in a particularly simple way to the local oscillator amplitude spectrum.
