High resolution array processing for direction - of - arrival estimation of underwater multiple targets by computer simulation method 水下多目標定向高分辨陣列處理的計算機仿真方法研究
It is well known that array processing technique is a main branch of underwater acoustic signal processing and multi - target parameter estimation 陣列處理是水下聲信號處理的重要組成部分,是進行水下目標參數估計的重要環節。
People try to use different means to eliminate the noise , such as adaptive cancellation , optimal array processing etc . but all these methods are complicated and expensive 對于這個干擾人們想了很多辦法來消除它的影響,自適應法是比較常用的方法,但是這種方法比較復雜,成本也比較高。
Independent component analysis ( ica ) is one of these methods . as a new array processing technique , ica is an effective means to resolve the bss problem 近年來隨著獨立分量分析( independentcomponentanalysis簡稱ica )在信號處理界引起的廣泛關注,該技術也被迅速應用到生物醫學信號處理領域。
In applications of array processing such as radar , sonar , and wireless communications , the array observed signal is best modeled as a distributed , rather than a discrete source 在雷達、聲納、無線通信等陣列處理應用環境中,由于存在豐富的多徑散射,陣列觀測信號更適合采用分布源模型來描述。
