Due to disadvantages such as over reliance for the ratio curve, low accuracy and poor anti-interference ability for traditional method of monopulse techniques in angle-measuring, a new scheme of monopulse technique based on Beam-Comparison is proposed. The essential idea of the proposed scheme is not to depend on the ratio curve, but obtain angle-information by comparing amplitude of beams. Comparisons...
In the broadband signal processing, in order to receiving broadband signals without distortion resulting from the different relative aperture, it is valuable to study the Frequency-invariant beam patterns (FIBPs). Based on the array structure, this paper will summarize some new methods to design a broadband beamformer with an FIBP. There will be two categories: One-dimensional arrays and Multidimensional...
