ASD software engineers also provide software design and programming for projects led by other MERC divisions.The ASD strives to produce innovative, cost-effective solutions to real world computer and electronic systems problems. The ASD employs a detailed system analysis approach to determine the best solution and then provides that solution in the most timely and cost-effective manner. The Applied Systems Division (ASD) is responsible for systems engineering, software development, technology insertion, and software maintenance and support for electronic and computer-based systems. The ASD leverages the skills of electrical engineers, computer scientists, mathematicians, and applied scientists to develop state-of-the-art electronic systems, apply new technologies to existing systems, and develop testing and support tools, models and simulations to support those systems.

The HPI System Analysis Model (HSAM) program leveraged the design of a previous system analysis model produced by MERC for testing an advanced pulse-deinterleaving algorithm. The HSAM system uses threat data tables from the AN/WLR-8 High Probability of Intercept (HPI) Electronic Surveillance system as input to a threat environment generator. The threat environment generation data contains the unique scan, pulse, RF, and radiation characteristics of each threat mode in the database for operation by the environment generator. The environment generator is driven by a scenario definition, in which the relative positions of the threats to the simulated platform, the predefined or randomly generated platform path and electronic order of battle are used to generate raw simulated RF data outputs to the receiver model kernel of the HSAM. The receiver model kernel operates on the raw data input from the environment generator. It provides a realistic set of receiver outputs to pulse descriptor word data files, which are formatted according to receiver look schedule data to provide collection buffers for execution either by the emulation processor. The receiver model kernel simulates the actual operation of the receiving, conversion, detection and preprocessing on the raw input data. These operations modify the data output for receiver anomalies such as spurious signals, images at band crossovers, transfer function inaccuracies, density driven pulse corruption levels as a function of bandwidth and recovery time of video amplifiers and detectors, system threshold impacts on timing accuracy and measurement, preprocessing and system shadow time effects on pulse buffer data.The emulation processor consists of the actual signal processor software from the WLR-8 rehosted to operate under the Linux environment. This signal processor is then connected to the actual control display processor for the system and provides actual expected system response to the input threat data. This tool is used for threat data file validation and for operator training when using a MERC-developed audio signal generator and pulse depiction utility that integrates with HSAM.
