Radar technology was designed to increase public safety on sea and in the air. Today radars are used in many fields of application, such as airdefense, air-traffic-control, zone protection (in military bases, airports, industry), people search and others. Classic pulse radars are often being replaced by continuous wave radars. Unique features of continuous wave radars, such as the lack of ambig...

Following the recent advancements in radar technologies, research on automatic target recognition using Inverse Synthetic Aperture Radar (ISAR) has correspondingly seen more attention and activity. ISAR automatic target recognition researchers aim to fully automate recognition and classification of military vehicles, but because radar images often do not present a clear image of what they detec...

Background A military aircraft in a hostile environment may need to use radar jamming in order to avoid being detected or engaged by the enemy. Effective jamming can require knowledge of the number and type of enemy radars; however, the radar receiver on the aircraft will observe a single stream of pulses from all radar emitters combined. It is advantageous to separate this collection of pulses...

DSSS (Direct Sequence Spread Spectrum) is one of the main technique of spread spectrum system and is the most common version use for military communication. In this paper, I have designed and implemented RADAR (Radio Wave Detection and Ranging) transmitter and receiver using direct sequence spread spectrum for range estimation. Most challenging part in RADAR system is to be getting better accur...

Inverse Synthetic Aperture Radar (ISAR) is a powerful radar processing technique which is capable of two and three dimensional high resolution image generation of the target. ISAR image is often regarded as an adequate and sufficient measure to discriminate between various targets like missiles, military aircraft and civilian aircrafts. However, if the target has complicated motion such as pitc...

The paper draws attention to the emerging military capabilities of laser radar by describing state-oftechnology sensor processing results for applications involving helicopter obstacle warning, automatic target identification at far range and automatic target detection and classification at close range. In all applications sensor processing requires accurate motion compensation using navigation...

A Digital Elevation Model (DEM) represents the height of a patch of terrain. Accuracies of DEMs vary depending upon the requirements of different applications. DEMs have been applied to a wide range of civil engineering and military planning tasks. Besides the conventional methods of creating DEMs, such as photogrammetry and manual field survey, airborne laser scanning and radar interferometry ...

Microwave is part of the electromagnetic spectrum that has different application such as communications, military, air-traffic Control and etc... Previous studies showed that radar frequency could be a health hazard agent. This review article mentioned some of the studies that investigated non-thermal effects of radar frequencies. Reproductive effects, cancers, blood effects, genetic, adverse i...

Radar Polarimetry Radar Interferometry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology, but we still need to progress very considerably in order to reach the limits of physical realizability. Whereas with radar polarimetry the textural fine-structure, target orientation, symmetries and material constituents can be recovered with con...

Ultra-wideband radar-based penetrating detection and recognition of human activities has become a focus on remote sensing in various military applications in recent years, such as urban warfare, hostage rescue, and earthquake post-disaster rescue. However, an excellent micro-Doppler signature (MDS) extracting method of human motion with high time-frequency resolution, outstanding anti-interfere...
