As the simple structure, Monopole antenna has been widely used in various communication systems. However, the narrow bandwidth of the monopole antenna always restricted their applications. The article presents a method to improve the bandwidth of the monopole antenna with graded multi-layer metal slabs. The measured results of the proposed monopole antenna show wide bandwidth between 2.9GHz and 3...
A novel design and related research of two-dimensional monopulse radar system with instantaneous polarization measurement capability is introduced. The radar system is designed to obtain and make effective use of the complete polarization scattering matrix (PSM) of radar targets. Polarization diversity technique is absorbed in both transmitting and receiving (T/R) paths. Orthogonal signals are used...
A base band sum-difference scenario used in digital monopulse end-guidance radar system is introduced in this paper. A method used to measure the microstrip array antenna pattern at base band is presented. The result shows that the antenna pattern in this design has much better performance at null-depth of difference beam than the traditional design. The angle measurement performance based on the...
