Abstract

This article contains information on EcoSAR. EcoSAR is the advanced airborne polar metric and single pass interferometric P-band SAR instruments under development at the NASA Goddard Space Flight Center, through NASA's instrument Incubator Program (IIP). EcoSar will provide two and three-dimensional fine scale measurements of terrestrial ecosystem structure and biomass onboard the NASA P3 aircraft. These measurements directly support science requirements for the study of the carbon cycle and its relationship to climate change. To evaluate plant growth on earth from an airborne platform, both construction of the radar and subsequent testing of the radar using advanced radar test equipment to help develop and improve the radar system was necessary. This article describes the development, testing, and deployment of the EcoSAR system.

Methodology

To obtain data and look and the productivity of the radar instrument, our EcoSAR team has come up with a methodical way to build and test the radar and eventually be able to test the whole system of radars to conclude that it is working to its full capability. The EcoSAR system has a front and back side. Each side has 2 trays with 4 boxes on each tray. The EcoSAR amounts to four trays and 16 boxes in one rack. Each box has to be constructed and tested before it can be mounted onto a tray (see Figures 1-4).

Wiring of EcoSAR

Once the box is received back from the mechanical engineer, coax cables are fed through with SMA connectors to the motherboard of the radar box. Each cable has an identified place on the connection to the mother board. In the 4 holes in Figure 2, two punched out SMA connecters are fed the through the circular holes, a power connecter and 25 dB are inserted through these holes.
