The experience, obtained in the local military conflicts during the past twenty years, shows persuasively that the radioelectronic war has great importance for the combat success. Due to this reason, the radiocommunication systems, including radars, are high priority targets. After finding of their location they are attacked immediately. For their destroying special intelligent rockets are desi...
We are interested in creating an automated or semi-automated system with the capability of taking a set of radar imagery, collection parameters and a priori map and other tactical data, and producing likely interpretations of the possible military situa tions given the available evidence. This paper is concerned with the problem of the interpretation and computation of certainty or belief in t...
Autonomous UGVs (unmanned ground vehicles) has been extensively investigated it’s capabilities for military applications. In order to operate the UGVs on the open fields, they must be able to detect obstacles (eg. holes, stumps, rocks, etc) concealed behind vegetation canopies, as well as to detect surface. Forward looking imaging radar is necessary to autonomous UGVs for collision avoidance an...
Microwave absorber are used in Military application, EMI reduction, Antenna pattern shaping, Radar cross reduction. Frequencyselective surfaces have been most commonly used in the radio frequency region of the electromagnetic spectrum and find use in applications as diverse as the aforementioned microwave oven, antenna radomes and modern metamaterials. One of the most important applic ations of...
Background and aim: Microwave radiations are one of the most environmental workplace factors that exposed too many workers. In microwave spectrum, radar frequency with 1-300 GHz range have varied applications such as satellite, communications, military, Network, navigation, air-traffic Control, navigation, marine and weather. Uncontrolled occupational exposure to radar radiation caused to vari...
In this paper we are explosively the fundamental theory of radar system modules STC (sensitivity time control) or sea clutter and FTC (fast time constant) or rain clutter. The STC and FTC are commonly used to some clutter. The radar signal is widely used for weather forecast, air port traffic control, military and fire control. The system implements radar processing procedures in real time mode...
RADAR is a ubiquitous technology used for everything from weather mapping to catching speeders on the highway. In the military, RADAR is one of the primary technologies used for engaging targets with missiles or anti-aircraft fire. The ability to deceive target locking RADAR can keep friendly pilots safe and allow them to carry out their mission. Techniques like “dumb jamming” are useful for ta...
For some years contributions about radiation exposures at radar facilities or radar devices of the German armed forces were published in the German media. A lot of Soldiers or other specialised workers who dealt with these devices before 1975 claimed their diseases as been caused by the radiation. In most of the cases and the resulting reports it is not distinguished between the high frequency ...
Doppler radar can be implemented for sensing physiological parameters wirelessly at a distance. Detecting respiration rate, an important human body parameter, is essential in a range of applications like emergency and military healthcare environments, and Doppler radar records actual chest motion. One challenge in using Doppler radar is being able to monitor several patients simultaneously and ...
