This paper describes the development of an array processing system and its integration into the local position measurement system (LPM). The design focus is laid on achieving high speed array processing performance in order to meet existing timing requirements. A field programmable gate array (FPGA) controls the radio frequency receivers and executes the array signal processing algorithms for local positioning. By physically separating the signal processing unit?s memory, the FPGA?s capacities can be fully exploited, and high signal processing throughput rates can be utilized. To verify the array receiver?s performance, measurements in a typical multipath environment are processed by the system.
