The Open Radar Data Acquisition (ORDA)
subsystem replaces the current WSR-88D Radar
Data Acquisition subsystem with improved
receiver and signal processing hardware and with
improved user interface, signal processing and
diagnostics software. This paper will discuss the
input data from the digital receiver, the ORDA
signal processing, and the data output from the
ORDA hardware. Specifications of the ORDA
digital receiver will be presented. The paper
outlines the critical radar signal processing flow
and provides analysis of new spectrum width
computations and clutter filtering schemes used in
the ORDA system. Where appropriate, ORDA
performance enhancements, data quality
improvements and reliability and maintenance
improvements will be highlighted.
To use the MSSP port to communicate with 3-wire
devices, the bytes to be output must be aligned
such that the LSB of the address is the 8th bit
(LSB) of a byte to be output. From there, the
bits should fill the byte from right to left
consecutively.
memcat - Copy the value of a key to standard output
memflush - Flush the contents of your servers.
memrm - Remove a key(s) from the server.
memstat - Dump the stats of your servers to standard output
memslap - Load generation utility (benchmark!)
