Websuch multiple bounce low-RCS design. A low-frontal RCS is important in aerospace vehicles. However, it is a real challenge to achieve this when a large radar antenna exists within the nose radome. Attempts have been made to reduce the frontal RCS by mounting the radar … A radar system relies on target reflection or scattering to detect and identify targets. The more strongly a target reflects, the greater the returned echo at the radar receiver, resulting in a higher signal-to-noise ratio (SNR) and likelier detection. In radar systems, the amount of energy reflected from a target is … See more The simplest target model is an isotropic scatterer. An example of an isotropic scatterer is a metallic sphere of uniform density. In this case, the reflected energy is … See more For targets with more complex shapes, reflections can non longer be considered the same across all directions. The RCS varies with the incident angles (also … See more Although computational electromagnetic approaches can provide accurate RCS predictions, they often require a significant amount of computation and are not … See more Wideband radar systems are typically defined as having a bandwidth greater than 5% of their center frequency. In addition to improved range resolution, wideband … See more

WebDownloadable (with restrictions)! In this paper, angular-diversity Radar Cross Section (RCS) based target recognition using Subsequence Dynamic Time-Warping (S-DTW) algorithm is proposed. The goal is to identify the similarity between an RCS segment of unknown and … RCS reduction is chiefly important in stealth technology for aircraft, missiles, ships, and other military vehicles. With smaller RCS, vehicles can better evade radar detection, whether it be from land-based installations, guided weapons or other vehicles. Reduced signature design also improves platforms' overall survivability through the improved effectiveness of its radar counter-measures. WebTo model an RCS pattern for an elevation cut (constant azimuth), you can specify the RCS pattern as a Q-by-1 vector or a 1-by-Q-by-K matrix. Then, the elevation vector specified in the Elevation property must have length 2.. To model an RCS pattern for an azimuth cut … floor plan column callout
