WebMar 15, 2024 · Reverberation chambers (RCs) were recently reported as a low-cost alternative to anechoic chambers (ACs) to perform radar cross-section (RCS) pattern measurements. The method consists of using transmitting and receiving antennas … WebThe incident wave excites currents on the scatterer (the target you are trying to illuminate) which then becomes an antenna re-radiating with its own antenna pattern. The power returned (P R) is measured by the radar cross-section (RCS), denoted . We define as the …
WebRCS Patterns 2. RESULTS The developed method for point scatter modeling based on RCS measurements can be summarized in three steps: 1. Target examination The RCS properties of the target are examined in order to determine which parts of the target that should be … WebApr 9, 2024 · The traditional measure of an object's scattering behavior is the RCS pattern which plots the scattered field magnitude as a function of aspect angle for a particular frequency and polarization.
WebSource: Introduction to Radar Systems, Second Edition, Merril I. Skolnik, page 44, 1980. At microwave frequencies average RCS can vary from 0.00001 m 2 for an insect to over 200 m 2 for a for a pickup truck. Depending on frequency a man measures about 1 - 4 m … 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.
