NISAR Installation

The CBI Field Operations crew installs a NISAR corner reflector, collaborating with NASA on a project aimed at advancing radar-based imaging capabilities for scientific research and monitoring purposes.

Each NISAR CR measures 2.8 meters (9.2 ft) and is a triangular-trihedral reflector constructed with 0.125" Aluminum Alloy 5052 H32 perforated sheets with staggered round holes of size 0.188". ​

​They are retained to the ground with 1/16" guy-wires pulled down to the ground with turnbuckles attached to duckbill anchors buried 18" into the ground. The front and rear wooden platforms rest on 2" high cinder blocks attached with wedge anchors and held down by 14" metal stakes.​

They do not require a power source or any maintenance post-installation and are used to: Acquire displacement measurements over areas that are densely vegetated – like marsh.
