A high - speed sampling system for echo signal of impulse gpr based on equivalent time sampling method is presented , and significant circuits including step sampling pulse generator and sampling gate circuit are designed 摘要提出了一種基于等效時(shí)間采樣方法的沖擊型探地雷達(dá)回波信號(hào)高速采樣系統(tǒng),設(shè)計(jì)實(shí)現(xiàn)了等效時(shí)間采樣的關(guān)鍵電路,包括步進(jìn)采樣脈沖發(fā)生器、采樣門電路。
Due to technology demand would carry out multi - place measure of wind pressure or negative pressure . because measured medium include high concentration coal powder and coal dust grain , often makes sample pulse pipe to stop up , and effect on correct measure of wind pressure , so to safety production causes serious menace 由于工藝上的需要,要進(jìn)行多處的風(fēng)壓或負(fù)壓的測(cè)量,因被測(cè)介質(zhì)中含高濃度的煤粉或煤灰顆粒,常使取樣脈沖管堵塞影響風(fēng)壓的正確測(cè)量,對(duì)安全生產(chǎn)造成嚴(yán)重威脅。
