Compensated PhD – A Sensor-Independent Product for Sar PhD

Abstract

Compensated Phase History Data (CPHD) is a standard data product for Synthetic Aperture Radar (SAR) phase history data. The CPHD product provides a sensor-independent data structure and file format for the transmission and storage of SAR phase history data. The data structure is designed to accommodate the Phase History Data (PHD) signal arrays from a variety of SAR sensors. The data structure includes a complete set of metadata that describe the collection geometry and the PHD signal arrays contained in the product. The CPHD structure supports both monostatic and bistatic SAR imaging data sets.The CPHD product is an adopted standard product of the National Geospatial-Intelligence Agency (NGA) of the U.S. government. The product enables the PHD from any SAR sensor to be processed by data processing systems that are developed independently of the SAR sensor.
