On radar polarimetry in FM-CW radar

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 ...

Scanning FM-CW radar sounder

1972 Antennas and Propagation Society International Symposium, 1972
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 ...

FM-UWB for Communications and Radar in Medical Applications

Wireless Personal Communications, 2009
UWB technology is a useful and safe new technology in the area of wireless body area network. There are many advantages of using UWB as a communication standard for biomedical applications. Due to very low radiated power (?41.3 dBm/MHz), low power consumption, good coexistence with the other existing instruments, Robustness to interference and ...

Designing Random FM Radar Waveforms with Compact Spectrum

ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
Spectrally-shaped random FM (RFM) waveforms have recently been shown to greatly expand radar design freedom, provide good spectral containment, and are amenable to physical implementation in high-power transmitters. A key design factor involves ways of enforcing a Gaussian spectral density via optimization, which leads to a Gaussian autocorrelation ...

Advanced polarimetric subsurface FM-CW radar

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.

Optimized FM PCL Radar Waveform

2006 International Radar Symposium, 2006
To make a balance between time of detection and resolution of detection in radar, it must select an optimized time interval for integrations and signal bandwidth. In this paper, a new algorithm for finding best width of window and bandwidth of the FM signals for FM PCL radar is designed.
