Radiation at Fixed Angle versus frequency
Sometimes, especially in radar applications, our aim is to control the shape of the pulse spectrum in the far zone at the particular direction from the transmitting antenna - rather than the radiation characteristic over a range of angles, at a few fixed frequencies. The NTF Fixed Angle (NTFFA) post-processing allows obtaining the Fourier-transform (spectrum) of the impulse response in the far field (radiation at a fixed angle defined as pair of Phi and Theta angles versus frequency). The results are available in the dedicated Results window. Direction information containing the pair of Phi and Theta angles is displayed in the status bar.
