Radar cross section can be efficiently estimated using PO solution (ray-tracing algorithm) in EMC Studio and EMCoS Antenna VLab software. This application note demonstrates calculation of Radar Cross Section of ship and comparison with analytical solution and RCS typical values.

Abstract: The letter evaluates the performance of a ship target's radar cross section (RCS) using a commonly used over-the-horizon radar's plane wave at 28 MHz. In contrast to prior work, we conduct a comprehensive analysis by simultaneously considering the following factors: (i) 3D modeling of a ship target, (ii) varying plane wave incidence ...

An obvious method of determining RCS is to put the object of interest, be it a ship or an aircraft, into a controlled environment and to use a calibrated radar system to measure the echo power.

Radar cross section (RCS) is the measurement of the reflective strength of a target, meaning that it decides how early a target can be detected. Reducing the RCS of a naval ship implies its late detection, which is key to surprise and initiative. The RCS of a naval ship is also important since

Abstract— The radar cross sections (RCS) of both small and large ships for High Frequency Surface Wave Radar (HFSWR) were studied by using Numerical Electromagnetics Code [4] and by using measurements from a HFSWR system at Cape Race, Newfoundland, Canada. The results of the study indicate that Teleost, a

RCS of ship depends on overall size and Gross/displacement tonnage of ship. Typical values for ships are known and described below: Median values for ship with approximate tonnage from 200-500 t are from 13 dBsm to 36 dBsm (highlighted rows).
