Putting Typhoid Vaccination on the Global Health Agenda

Typhoid fever is still a substantial cause of illness and death in many developing countries. But Denise DeRoeck, Luis Jodar, and Dr. John Clemens write that vaccination against typhoid fever has largely fallen off the international radar screen.

Passive radar using Global System for Mobile communication signal: theory, implementation and measurements

Passive radars using illuminators of opportunity have attracted much attention in the international radar community. One existing radio transmission system that may be utilised for this purpose is the Global System for Mobile communication (GSM). The paper presents a study showing the feasibility of using a GSM signal for passive radar. The analysis of the GSM waveform, and any significance or influence it has with respect to the passive radar design considerations are investigated in detail. The paper describes fully the design and implementation of a low-cost GSM-based passive radar prototype in addition to the associated signal processing scheme. Numerous measurements for various ground-moving targets were investigated extensively. The preliminary processing results demonstrate the feasibility of using GSM signals as a radar waveform and have the potential capability to detect and track different types of ground-moving targets.

Ultra-wideband technology and random signal radar: an ideal combination

Ultra-wideband radar and random signal radar are two types of newly-developed radar systems. This paper introduces the special advantages of the combination of ultra-wideband technology and random signal radar to the international radar community. It shows that these two radar systems have a very close relationship in nature and can gain significant benefits from each other. It can be anticipated that the random signal modulated waveform will open many potential possibilities for the applications of ultra-wideband radar systems to civilian operating environments.

GRS 2002: German Radar Symposium in Bonn, Germany

The German Radar Symposium (GRS 2002), organized jointly by the German Institute of Navigation (DGON) and by the Information Technology Society (VDE-ITG), attracted wide interest in the international radar community. It was held from September 3-5, 2002, in Bonn, the former capital city of Germany. The GRS 2002 programme covered a large scale of important radar topics. All classical topics like air traffic control, CFAR, antenna technology, signal processing and simulation papers have been presented and new results were demonstrated. These topics were combined with new applications like meteorology, subsurface, and automotive to underline the increase of interest in radar technology. Phased array antennas are the key elements of high performance multi-function radar systems which are studied all over the world. SAR and ISAR are, nowadays, essential radar techniques for civil and military observation and monitoring.

The multifaceted peter swerling

As the banquet speaker for the 1975 International Radar Conference, Peter Swerling's fascinating talk about how he became involved in target fluctuation models, Jess Marcum’s gambling escapades, and his own education, was thoroughly enjoyed. Unfortunately it was not captured on tape, and no one thought to ask for a copy of his notes. I remember asking him about it again during the 1999 Radar Conference: at that time he indicated that he could not find them. They bear repeating.

Precipitation in the Northern Alpine Region: Case-Study-Type Validation of an Operational Forecast Model

Quality and limitations of current quantitative precipitation simulations are determined using the Deutschland-Modell of Deutscher Wetterdienst (DWD). The model independent validation data comprise the regular rain-gauge network of DWD, taylored composites of an international radar network, Doppler winds from the DLR research radar, and meteorological timeseries at a ground station. Area skill scores are compared for convectively dominated as well as more synoptically forced situations in the northern Alpine region. Inspection of the temporal evolution of the components comprising the atmospheric water budget and of the precipitation partition gives insight in the different nature of excitation mechanisms of heavy precipitation. The simulations are found to exhibit growing potential for follow-on hydrological applications, while a real break-through appears to necessitate the coming generation of non-hydrostatic operational forecast models with increased spatial resolution.

Comments suggested by "Target tracking with a network of Doppler radars"

The writer has been collecting information on current radars for the forthcoming International Radar Directory CD-ROM. He has collected open information on radars of the world; for over 20 years to date he has identified 9,800 radars from about 400 manufacturers in 30 countries. He claims that it would be helpful for authors to prepare a short addendum to their paper to briefly present the technical characteristics of any Doppler measurement hardware contained in their references.

Comments on "HAL-3 radar test set"

The author comments on a paper by Fang, Z. et al. published in ibid., vol. 30, no. 3 (July 1994). He suggests that a brief description of the HAL3 radar would have given the Transactions reader a better understanding of the function of this test set. The HAL-3 radar was developed by SUST for installation in the Chinese civil Y-10 transport aircraft, but that was cancelled. The HALS is an airborne weather radar which also provides navigation capability. A combination of functions is rare according to information in the International Radar Directory files on radars of the world. It operates at X-Band with a peak output power of 60 kW, a pulse-repetition frequency (PRF) of 400 pps, pulsewidth of 2.2-2.5 us, antenna gain of about 36 dB, and receiver noise factor of approximately 10 dB. In the navigation role it can detect the drift angle with a I deg accuracy and simultaneously measure aircraft ground speed. It has conventional weather radar capability. The test set can be used with many airborne weather radars though appropriate interface cables. Use of extensive display information in the language of the user (presently in Chinese) makes this test set extremely user friendly for radar maintenance technicians. >

Radio, rocket, and radar recollections

Three phases of my association with Sir Granville Beynon over a period of more than forty years are recalled. The first relates to postgraduate studies based on ionospheric radio-sounding experiments during the establishment of his research group at the University College of Swansea in the early 1950s. The second is concerned with a joint research programme between the Radio and Space Research Station, Slough, and Aberystwyth, but involving other national and international groups, which Sir Granville directed. The third refers to my period as his successor at Aberystwyth where much of the research activities benefit from national and international radar facilities available largely because of Sir Granville's foresight and influence.
