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 ...

Designing Random FM Radar Waveforms with Compact Spectrum
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021Spectrally-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 ...

FM-UWB for Communications and Radar in Medical Applications
Wireless Personal Communications, 2009UWB 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 ...

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.

Optimized FM PCL Radar Waveform
2006 International Radar Symposium, 2006To 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.

Mathematical model of FM autodyne radar
2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016The mathematical model of operation of frequency modulated autodyne radar is developed. The model is presented in the form of an oscillator situated under influence of the proper reflected radiation from a radar object and inherent oscillator noises. Options of frequency modulation in the supply circuit and by means of capacity variation of the varicap

Electronics & Communication Engineering Journal, 1990
FM radars represent one of the oldest and simplest–yet at the same time one of the most versatile types of radar. The paper presents a tutorial review of the basic principles of FM radars and introduces a number of new ideas, including digital generation of wideband linear FM waveforms, and aperture synthesis with FM radar.

IEE Proceedings - Radar, Sonar and Navigation, 2005
An experimental bistatic radar system is described that detects and tracks targets to ranges in excess of 150 km from the receiver, using echoes from a non-cooperative FM radio transmitter. The system concept and limitations on performance are described, followed by details of the processing used to implement the system. An adaptive filter algorithm is

MIMO-FM: A Solution to Estimate Target Elevation with Passive FM Radar
2018 International Conference on Radar (RADAR), 2018In this paper, we deal with the problem of estimating the target elevation in passive FM radar. Due to the large wavelength of such systems, accurate beamforming at the reception side would require unpractical large reception devices of several meter height.
