Demonstration of Real-time Cognitive Radar using Spectrally-Notched Random FM Waveforms
Radar, 2020With the reality of increasing radio frequency (RF) spectral congestion, radar systems capable of dynamic spectrum sharing are needed. Recent work has demonstrated a real-time cognitive capability on a software defined radio (SDR) by generating pulse ...

MIMO-FM: A Solution to Estimate Target Elevation with Passive FM 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 ...

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

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.

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

Long range FM-based passive radar
IET International Conference on Radar Systems (Radar 2012), 2012The paper presents the concept of the long range passive radar utilizing the FM-radio transmitters as illuminators of opportunity. The concept has been verified via the analytical analysis, simulations and real measurement campaign. The confirmed detections of the air targets at long range (up to 300 km monostatic range) has been obtained using the ...

At IRCTR, a collision avoidance radar demonstrator (Colarado) for autonomous vehicles is under development. The radar task is to avoid collisions by detecting the presence of obstacles and by determining the obstacle positions and velocities in the near range of the radar. In the years 1996-1999, an X-band (centre frequency 9.75 GHz, bandwidth 1.5 GHz)

Coherent FM-CW millimeter-wave radar systems for radar cross-section measurements
6th IEEE Conference Record., Instrumentation and Measurement Technology Conference, 1990Coherent instrumentation radars have been developed at 35 and 94 GHz for use in radar cross section measurements at angles of incidence ranging from 0 degrees to 60 degrees . The systems are designed to measure the radar cross section of various targets, at like and cross-polarizations, in an effort to better understand their scattering characteristics.
