Abstract The MCARM program is a Rome Laboratory sponsored effort initiated in 1991 to collect airborne phased-array radar data used in studying advanced processing techniques and technologies which will be required to support the mission requirements of next generation airborne early warning (AEW) platforms. The MCARM program is the most recent of a long series of experimentation and exploration that both Westinghouse and Rome Laboratory have pursued in the area of adaptive radar processing. This program is collecting data to support the evaluation of Space-Time Adaptive Processing (STAP) algorithms and the characterization and modeling of monostatic and bistatic scattering. The data will be made available to the adaptive processing community for their use and exploration of adaptive processing algorithms.

The basic system characteristics include 2 kW of transmit power, and 24 receive channels at L-Band, mounted on a BAC-111 aircraft. The radar and associated data is recorded on a high speed recording system for later data analysis. The system also has an analog fixed beamformer for comparison purposes. Monostatic data collection began in November 1994. Bistatic data collection, and additional experiments are planned for May 1995 and beyond.

This presentation provides an overview of the program including detailed characteristics of the radar, the data collection system, and the data collected thus far. It also outlines future plans for the program.
