RCS Patterns In Figure 4, RCS patterns are shown as objects are r otated about their vertical axes (the arrows indicate the direction of 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.
