Evaluating the performance of several types of antennas in a holographic radar with continuous wave

The experiment examines the performance of the logarithmic spiral antennas, Vivaldi antennas and dipole antennas when operating in continuous wave radar based on a chirp signal. Evaluation of the spectrums of the received signals shows that the use of the separation shield can effectively reduce mutual coupling. It also concluded the feasibility of constructing the antenna system holographic radar as a pair of transmit and receive logarithmic spiral antennas.
