Perhaps you should try some spelling variations:
"based integration radar" » "based interaction radar", "based information radar", "based interactive radar", "based integrating radar", "based integration roadmap", "based integration random"
"based generation radar" » "based genetic radar", "based generation raman", "based generation radio", "based generation random"
"sound generating random" » "sound generation random", "und generation random", "und generative random"
"sound generated random" » "sound generalized random", "sound general random", "sound related random", "sound generation random", "wind generated random"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("based generation radar") OR ("based integration radar"))) OR ((("sound generating random") OR ("sound generated random")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"based generation radar\") OR (\"based integration radar\"))) or (((\"sound generating random\") or (\"sound generated random\"))))".
• Removing quotes may allow a broader search: (((( based generation radar ) OR ( based integration radar ))) or ((( sound generating random ) or ( sound generated random )))).
• Adding a wildcard symbol may retrieve word variants: (((("based generation radar") OR ("based integration radar"))) or ((("sound generating random") or ("sound generated random"))))*.
