Spectrum Engineering may be defined as a set of techniques that are being developed in response to the pressure on the RF spectrum that comes as a result of increased demand for spectrum. The aim of his paper is to explain the nature of this problem, and some of the techniques and approaches to regulation that may be used to address it.
In the antimissile context, it is important to detect and resolve the unresolved targets in the middle of the ballistic flight. As the targets in group are very close to each other, the traditional techniques are difficult to resolve them. In this paper, we study the problem of grouped target resolution in the angle dimension with array radar. We first establish an echo model of the array radar when...
Modern semiconductor technology, such as small geometry CMOS, is providing the opportunity to build very small and very low cost single chip radar systems operating at millimeter wave frequencies. Such tiny radar systems open up a vast range of new applications from automotive radar, safety helmet radar, bicycle radar, health monitoring radar, robot guidance radar, micro-UAV surveillance radar, and...
The optimal design of chirp radar waveforms has to satisfy conflicting requirements. Optimal solutions for different values of the compression ratio are considered, evaluated and compared with each other. A proposed solution has the advantage of guaranteeing low range sidelobes (less than −50 dB below the peak for compression ratios greater than 256) while maintaining the transmitter to operate in...
Multi-input Multi-output (MIMO) radar has drawn considerable attention in recent years. The waveform design has the most important influence on the performance of MIMO radar, thus having been an active area of research. In this paper, the orthogonal signals generated from OFDM signals are proposed in the application of uniform linear array (ULA) MIMO radar. Matched filters are applied at the receiver...
Within the frame of the Eurad-2014 Special Session «110 years of radar developments in Europe after Hülsmeyer's Telemobiloskop» this introductory paper contains (i) a retrospective analysis of the present literature and of its missing elements and (ii) a kind of presentation of this Special Session and its rationale.
