STUDY OF TIME SAMPLING AND PHASE ADJUSTMENT BEAM STEERING TECHNIQUE
-
摘要: 本文发展了一种用于宽带雷达阵成象的计算机化的时间取样相位调整技术。同时提出了检验时间取样所引起的误差的算法。对于周期阵,还利用FFT来加速成象数据处理。模拟结果和实验数据都表明此技术是可取的。

Abstract: A computerized technique including time sampling and phase adjustment is developed for wideband radar array imaging. Algorithms are given for examination of errors due to time sampling, FFT is introduced to speed up the imaging processing with a periodic array. Simulation results aud experimental data are included to show the feasibility of the technique. -
