spatial-domain filtering 中文意思是什麼
spatial-domain filtering
解釋
空間區域過濾-
For slow targets whose doppler frequencies fall into clutter doppler band, the performance of frequency domain one - dimension filtering is seriously degraded. in an airborne radar, there is interdependence between the clutter doppler frequency and spatial position. space - time adaptive processing ( stap ) utilizes this interdependence to suppress clutter and get perfect main - lobe and side - lobe clutter suppression
空時自適應處理利用機載雷達地雜波多普勒頻率與地雜波空間位置的耦合性，根據目標和雜波在空間-多普勒頻域二維空間分佈上的差別對雜波進行抑制。 -
Therefore, based on the ann correlation signal post - processing technique, we designed a kind of sdf performed in spatial domain, and a two - step recognition technique was introduced to perform real - time distortion - invariant recognition by combining frequency domain filtering of sdf with spatial domain filtering of sdf
為此，本文在ann相關信號后處理技術的基礎上引入了二次識別技術，設計製作了一種空域執行的sdf濾波器，採用頻域sdf濾波與空域sdf濾波相結合的方法，對目標進行實時畸變不變識別。 -
The first step, the infrared imageconverted from spatial domain to fuzzy field, then itenhanced by homomorphic filtering, at last, the processed image is obtained
該方案首先將紅外圖像由空域平面轉換成模糊域（特徵）平面，然後再對其進行同態增強，最終經去模糊得到處理后的圖像。 -
As analyzing the optical spatial filter and frequency domain filter with wavelet transform, the space variable processing > matched filtering and imagery system are the examples. all of these confirm the feasibility of wavelet transform applied in optical information processing
用小波變換處理光學信息，主要的是應用小波的多分辨特性，小波變換的定義是一相關運算，很容易在光學系統中實現，這是光學小波變換的理論依據。
