Here is what my dataset looks like: Theta [deg.] Phi [deg.] Abs(RCS )[dB(m^2)] AbsA radiation pattern plot may be a 3D plot or a pair of 2D plots. In addition, this app can also help user to prepare virtual matrix from the raw data. The CAROLINA WINDOM® was the first antenna to take advantage of 'VERT™' (Vertically Enhanced Radiation Technique). Also, the radiation pattern is a graphical depiction of the relative field strength transmitted from or received by the antenna. A radiation pattern is usually represented graphically for the far-field conditions along the electrical field and the magnetic field vectors, along the direction of maximum radiation or E-plane and H-plane.
