On radar polarimetry in FM-CW radar [PDF]
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002 This 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 ...

Advanced polarimetric subsurface FM-CW radar [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 1998 The 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.

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.

Wind velocity observation with a CW Doppler radar
IEEE Transactions on Geoscience and Remote Sensing, 2002We study the problem of gathering information about wind velocity from continuous-wave clear-air Doppler radar measurements. The radar is assumed to be a monostatic fixed-frequency Doppler radar, and the wind velocity as well as the reflectivity are modeled as random fields with statistical parameters depending on the altitude.

Design of A CW-SF Ground Penetrating Radar
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Most of Ground Penetrating Radars (GPR) are pulsed system, nevertheless there are a number of applications for which Continuous Wave Step Frequency (CWSF) radar can be advantageous. Generally speaking, CWSF systems are more complex then pulse radar, but they can manage larger bandwidth, have larger time efficiency and better control of the band ...
