Successful VSIPL Software Application Migration. A Case Study: NATO Seasparrow Illumination Radar Signal Processing
Abstract
An embedded weapon system signal processing software application involving 10K SLOC was converted from vendor proprietary middleware to that vendor's VSIPL implementation, deployed aboard US Navy surface combatants, and then ported without modification to a less expensive hardware platform using a different vendor's commercially available VSIPL product. This successful episode of software portability offers an opportunity to assess the utility of VSIPL in the context of a production military application, and yields user and vendor strategies and forecasting information for similar future efforts to cost-effectively leverage the products of this research community. The NATO Seasparrow ship self defense missile is guided to a maneuvering high velocity inbound target by a ship based 10.125 GHz illumination radar. At 43 Hz, the radar receiver time series is digitized and processed for tracking data products. Inbound targets manifest as Doppler shifted energy spikes in the frequency spectrum. A conically scanned receive antenna scheme imparts amplitude modulation across the time series for off-center targets. A 2 KHz carrier frequency modulation smears the Doppler shift of a target over multiple frequency bins as a function of range. The Naval Research Laboratory (NRL) developed a modest set of signal processing algorithms modeled in MatLab to yield track velocity, traverse and elevation angle errors, estimated range, and audio-video spectral representations given the input time series. The software implementation of these algorithms served as the study case for this VSIPL application migration effort.
