== History ==<br />
''Examine the history of the creation and combat usage of the radar in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the radar and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Radar-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>.''<br />
