A laboratory method to determine the magnitude and position of radar reflection sources on complex targets is described. In addition the method provides a way to measure the modification of the radar cross section (RCS) due to multipath. The method has application in modeling RCS for radar and electronic countermeasure (ECM) system performance analysis

Radar Cross-Section of Potholes at Automotive Radar Frequencies
2020 IEEE International Radar Conference (RADAR), 2020Automated detection of potholes in roads can increase driving safety for both passengers and vehicles. Potholes - especially those covered with water - are hard to detect using cameras, while vibration based detection using accelerometers cannot be used to find potholes ahead of the ego vehicle.

SPIE Proceedings, 2011
From the begining of military warfare, it has always been extremely important to know the enemy position and hide oneself to capitalize on elements of surprise and initiative, and same is true for naval warfare. Radar is the primary instrument used for detecting enemy platforms today.Radar detects a target by clocking time taken by a known pulse of ...

Radar-Absorbent Material and Radar Cross Section
2020Radiation-absorbent material, usually known as RAM, is a material which has been specially designed and shaped to absorb incident RF radiation, as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected radio-frequency (RF) radiation.

Radar cross section (RCS) is a measure of the electromagnetic energy intercepted and reradiated at the same wavelength by any object. The dimensions are those of an area, usually square meters. The object of interest is compared to an idealized object that is large with respect to a wavelength, has an intercept area of one square unit, is perfectly ...

Radar cross-sectional study using noise radar
SPIE Proceedings, 2015A noise radar system is proposed with capabilities to measure and acquire the radar cross-section (RCS) of targets. The proposed system can cover a noise bandwidth of near DC to 50 GHz. The noise radar RCS measurements were conducted for selective targets like spheres and carpenter squares with and without dielectric bodies for a noise band of 400MHz ...

Radar Cross Section Enhancing Structures for Automotive Radars
IEEE Antennas and Wireless Propagation Letters, 2018As automotive radar and driver assistance systems prevail, weak scattering targets such as pedestrians and bicycles can be applied with radar cross section (RCS) enhancing structures to improve road safety. Low-profile structures, which comprise straight and ring-shaped ridges mounted on metal plates, are developed in the 24 GHz band to provide the ...

Radar cross section measurements of the human body for UWB radar applications
2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2012An experimental set-up for mono-static radar cross section measurements in the 1 – 10 GHz frequency band, employing an anechoic chamber, is presented and validated. The test range is calibrated by means of a readily available aluminum flat panel and its performance is tested against canonical metallic and lossy dielectric targets.

Radar cross section measurement with 77 GHz automotive FMCW radar
2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016In this paper, radar cross section (RCS) measurement for human subjects and vehicles in 77 GHz automotive frequency modulated continuous wave (FMCW) radar system is presented. In this system, it is impossible to utilize conventional RCS definition due to high frequency band and the modulation technique used.
