Drone object avoidance

I'm looking for a good radar device to use for drone object avoidance.  All the information is geared toward automotive.  

I need a radar that has -

approx 45 degrees H & V  FOV

ability to detect small objects like wood and metal utility poles and (hopefully) utility wires at > 15M distance.

ability to detect trees and other vegetation at  > 30M distance.

lightweight.(200g or less) preferable and small.

Update rate of at least 10Hz.

distance accuracy +/- 3 M.

Low cost (<  $350).

Analog, SPI, RS-232 or I2C output.

Can anyone tell me where I can find a completed unit that can meet the specs above?
