Defect location , representative defect and its ultrasonic echo characteristics corresponding of tungsten alloy shells had been systematically studied by both vertical wave sensors and transverse wave sensors calibrated after manufacturing 摘要采用縱波直探頭和自磨制經(jīng)校準(zhǔn)的斜楔橫波探頭,對(duì)鎢合金殼體部件進(jìn)行了檢測(cè),并對(duì)鎢合金殼體的缺陷定位、典型缺陷及其對(duì)應(yīng)的回波特征進(jìn)行了研究。
This article , through analysis different system radar ’ s superiority and limitation in target identification , proposes to unite the convention air defense radar ’ s echo characteristic and the electronic support sensory system ’ s aircraft - borne radiant characteristic , structure reasonable recognition system . it can satisfie the airplane target identification demand under the different background 本文通過分析不同體制雷達(dá)在目標(biāo)識(shí)別上的優(yōu)勢(shì)和局限性,提出把常規(guī)防空雷達(dá)回波特征和電子支援偵察系統(tǒng)得到的機(jī)載輻射源特征聯(lián)合起來,構(gòu)造合理的識(shí)別系統(tǒng)的新思路,以此來滿足不同背景下對(duì)飛機(jī)目標(biāo)識(shí)別的需求。
