An Analysis for Ground Diffraction about Detecting beyond the Horizon Using Television-Based Bistatic Detection System

Abstract:

Analysing the characteristics of a television transmitter carefully, the paper compares the television-based bistatic radar with the conventional monostatic and bistatic radar on targets detecting beyond the horizon in some given direction. In the light of the effect of ground diffraction produced by electromagnetic wave propagation on different radar ranges, it is shown that television-based bistatic radar has a potential advantage over conventional radar in targets detecting beyond the horizon because of its particular advantages in height gain and diffracting efficiency. At the same time, we have an in-depth study which is the decisive factor on radar ranging, height gain or diffraction effect, conduct an effective method of how determine the optimal wavelength so as to get the maximum radar detecting range.
