The radar arithmetic processing element as an MTI filter
Abstract
The Radar Arithmetic Processing Element (RAPE) was designed, developed, and built to demonstrate the feasibility of performing a subset of radar predetection signal processing algorithms in real time via a program-controlled processor. The organization of the machine reflects the similarity of the kernels of various signal processing tasks. Multiple functional units, including memories, multipliers, and adders are simultaneously controlled and sequenced by a microprogram stored in a programmable read-only control memory. High-speed operation is obtained by both functional or horizontal concurrency and pipelining or vertical concurrency. The RAPE has been successfully utilized as an MTI processor in an actual radar environment. The RAPE was programmed to perform various second-order filter configurations over 512 range gates (approximately 40 miles). This allowed stationary clutter within a 40-mile range to be canceled, while moving targets within this range were passed.
