Radar Processing Unit

The Radar Processing Unit is used for airborne radar signal processing and radar timing generation. The Radar Processing Unit consists of Digital IF (DIF) receiver boards, Radar Timing and IO generator (RTIO) boards along with signal processing boards. It is built on a custom VPX multi-slot backplane which accommodates the various boards.

The entire setup is enclosed in a forced air conduction cooled (FACC) ATR chassis. Designed for strength and maximum cooling in a conduction cooled environment, the chassis incorporates brazed folded fin material thermally bonded between the conducting side walls and the outer side panels.

The chassis is EMI/EMC compliant to MIL-STD-461E. The external world IF signals interface with the DIF board on blind-mate RF connectors (BMA-type). All other boards are VPX VITA-46 compliant, which ensures that individual cards are easily replaceable and hence the system maintainability is improved.
