Use of pseudo-orthogonal sequences in phased array systems for simultaneous scanning in multiple directions

摘要

the use of phased techniques array coded excitation from a set of sequences pseudo-orthogonal, such as proposed derivative pseudorandom sequences or CSS (Complementary Sets of Sequences) and subsequent process step, all this allows to obtain images of the environment with high resolution from one issue simultaneously covers multiple different directions of the environment, unlike conventional phased array systems that require a broadcast by each sector to be inspected. This invention introduces a new method of driving the array elements and post-processing the received echoes increases speed imaging, and the maximum distance to inspect maintaining image quality.
