美將開發出口型相控陣雷達與F35所用雷達相當
本帖最後由 MightyDragon 於 2012-9-25 12:28 AM 編輯實際上它是不是一種新產品：只是F-35使用的前台天線結合SABR的後台處理器。從這篇文章中我認識到APG-81沒有後台處理器！就好像殲-20一樣，第四代戰鬥機使用綜合航電系統（例如F-35的寶石台系統）管理各傳感器包括雷達從而優化電源管理，所以APG-81不能直接使用在舊式戰鬥機上。這條消息也反映諾斯羅普·格魯門公司對其產品SABR雷達的信心是不足夠的，否則沒有必要推出新的產品

Northrop Grumman to pitch new AESA radar to export customers
Northrop Grumman plans to offer a new radar based on the antenna of the Lockheed Martin F-35 Joint Strike Fighter's (JSF) APG-81 active electronically scanned array (AESA) combined with the receiver, exciter and processors (REP) of its Scalable Agile Beam Radar (SABR) to potential foreign upgrade customers.
Northrop has already test flown the new radar on its British Aircraft Corporation BAC 111 test-bed aircraft, says Patrick Antkowiak, vice president of the company's advanced concepts and technologies division.
"We put it on there in literally weeks and flew it on May 9th," Antkowiak says.
The new system would have the power and performance of the APG-81, but at much lower cost.
The SABR REP cannot be retrofitted back into the F-35 because APG-81 does not have a "backend" as such, instead most of the processing for the radar is performed in the JSF's core processors, says Joe Ensor, Northrop's vice president for intelligence, surveillance and reconnaissance and targeting systems.
Antkowiak says that though the new radar will be offered to both foreign and domestic customers, the radar is most likely to be offered for export to customers flying the Boeing F-15, F/A-18 or Lockheed F-16. That is because US F-15s and F/A-18s are already being upgraded with Raytheon-built AESA radar sets.
One of the advantages of using the APG-81 antenna is that it is already cleared for export, Ensor says. Therefore, it should not be difficult to get the new radar cleared for sale to foreign allies. ...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div><div></div> 其實APG-81沒有後台處理器蠻正常的
包括俄羅斯T-50在內的所有5代機都是使用中央處理器
因為對於現在的產品沒有信心
所以又繼續推出新產品以保住市場嗎{:32:}
這不是很正常嗎 一直不斷創新 先推出產品在換更好的這才能賺錢 翻譯過來就是：我們將在F-35的雷達上偷工減料，並增加幾個後門~<br><br><br><br><br><div></div> 科技進步,這些當然會有所改變,但是不變的是台灣還是在當白老鼠 這是美國一貫的貿易手法
先推出次產品是水溫，若真不行再進行微調
