摘要: 本文發(fā)展了一種用于寬帶雷達(dá)陣成象的計算機(jī)化的時間取樣相位調(diào)整技術(shù)。同時提出了檢驗時間取樣所引起的誤差的算法。對于周期陣,還利用FFT來加速成象數(shù)據(jù)處理。模擬結(jié)果和實驗數(shù)據(jù)都表明此技術(shù)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. -
