Experimental study on target echo characteristics for forward scattering radar
Forward scattering radar is a particular bistatic radar scheme with the bistatic angle approaching 180°. According to the total field variation, the forward scattering radar can detect the target when targets pass through the baseline. Therefore, the research on echo characteristics of forward-scattering radar is of great significance. The effects of coherent superposition of scattering and radiation fields are analyzed based on the measurement data of metallic sphere, dihedral, trihedral, and cylinder radar targets in an anechoic chamber. It is summarized that when the radar target enters the forward scattering zone, the echo amplitude decreases firstly, and then rebounds slightly. This work helps to improve the knowledges about forward-scattering radar echo characteristics, and provides supports for the target detection and recognition technologies.
