New Phased Array designs allow electronic radar beam forming and low cost production for military and industry

In his PhD thesis, Danial Ehayaie presents three new approaches to the design of phased array antennas in order to reduce their complexity. First approach based on extended resonance technique achieving power dividing and phase shifting within a single circuit. In the 2nd approach, the author applies a bi-directional feeding method. This approach demands less […]

FOURIER TRANSFORM METHODS IN GEOPHYSICS

  David Sandwell introduces into the use of Fourier transform in geophysics such as image processing,time series analysis, and antenna design. He focusses “on the use of fourier transforms for solving linear partial differential equations (PDE). Some examples include: Poisson’s equation for problems in gravity and magnetics; the biharmonic equation for problems in linear visco-elasticity; […]

FMCW Phased Array Radar for Automatically Triggered Measurements of Snow Avalanches

By Brennan et al. In the abstract, Brennan et al. write: “Radar has emerged as a means of measuring avalanche dynamics for validating models to predict avalanche behaviour for improved calculation of risk zones. However, current radar measurements do not provide a true representation of an entire avalanche flow. An FMCW, multi-chirp, 8 receiver channel […]

BISTATIC RADAR OBSERVATIONS OF THE MOON

BISTATIC RADAR OBSERVATIONS OF THE MOON USING THE ARECIBO OBSERVATORY & MINI-RF ON LRO By Bussey et al. NASA successfully used a bistatic ground radar to measure the moon’s surface. “The bistatic angle is determined by the positions and orientations of the radar transmitter and receiver. […] NASA’s Mini-RF instrument on the Lunar Reconnaissance Orbiter […]

Multi-target detection algorithm for FMCW radar

by Hyun et al. The authors conduct research on multi-target detection algorithms. In their abstract, they state that “FMCW (Frequency Modulation Continuous Wave) radar has been a popular method for automotive applications. The typical FMCW radar, however, has serious problems in multi-target situations. That is, range-velocity processing gives rise to so-called ghost targets due to […]

Radar-Based Detection and Identification for Miniature Air Vehicles

In their paper “Radar-Based Detection and Identification for Miniature Air Vehicles” Moses et al. give valuable insight into the detection and identification of drones through an x-band radar. Here the abstract: “It is claimed that Unmanned Aerial Vehicles (UAVs) used for civilian/public domain applications will be dominant in the near future. Compared to UAVs used […]
