To filter collection in MongoDB with radius at first create the geospatial index.

If your collection name is user then 

db.user.ensureIndex({loc:"2d"})

You need to convert the radius value to km. By default mongodb $near accepts $maxDistance as radius.

Now you can search within 1km radius

 db.user.find({ loc : { $near : [yourLat,yourLon] , $maxDistance : 100/111.12 } } )

for more MongoDb version 2.2 doc
