A new technique to enhance the indication of moving targets is proposed, which makes use of randomized Stepped Frequency Continuous Wave (SFCW) modulations, where the frequency order is changed from pulse to pulse. This kind of signals gives the possibility to discriminate tar ...

This paper presents a novel approach for processing data acquired with Frequency Modulated Continuous Wave (FMCW) dechirp-on-receive systmes by using a non-linear frequency scaling algorithm. The range frequency non-linearity correction, the Doppler shift induced by the continuou

In the field of airborne earth observation there is special attention to compact, cost effective, high resolution imaging sensors. Such sensors are foreseen to play an important role in small-scale remote sensing applications, such as the monitoring of dikes, watercourses, or hig

The combination of Frequency Modulated Continuous Wave (FMCW) technology and Syntehetic Aperture Radar (SAR) leads to lightweight, cost-effective imaging sensors of high resolution. In rithms cannot be considered valid anymore, so the motion within the sweep needs to be taken int

In some earth observation applications there is a requirement for low cost, high performance imaging radar systems small enough to be operated from small, even unmanned, aircraft. The existing pulse radars are non-cost effective complex systems. Therefore they are not suited for

Airborne synthetic aperture radar is a promising new application for FM-CW radars. At the IRCTR, an operational demonstrator system has been developed in order to investigate practicability of FM-CW SAR and to prove that and FM-CW SAR an FM-CW SAR system can be operated in an eff
