A strictly physically based design theory of a new class of Spatial Harmonic Magnetrons (SHM) is thoroughly derived which leads to analytically evaluable expressions. Thus two advantages are obtained: (1) The design parameters appear grouped into two

The remarkable progress in millimeter-wavelength radar and communication systems has given a strong motivation for further developing slotted waveguide antennas. In this paper, a novel W-band monopulse antenna is presented. The antenna represents a c

The paper presents a high-power compact RF front-end for X-band weather radar applications. The front- end benefits from a novel high efficiency GaN SSPA with 900 W peak power, a low noise receiver, and a low noise fast-switching local oscillator. Ci

High-resolution imaging with an airborne synthetic aperture radar (SAR) calls for precise trajectory measurements that can hardly be achieved with common navigation systems. In this paper, an efficient method called the local-quadratic map-drift auto

A chirplet transform-based algorithm is analyzed as a mean for detecting radar targets moving with a constant acceleration. The ambiguity function of the chirp signal associated with radar return from such targets is presented in an analytical form.
