    Co-processor offloading applied to passive coherent location with Doppler and bearing data
    (2010) Milburn, Joe; Inggs, Michael
    This project dealt with the acceleration of an aircraft tracking algorithm using a ClearSpeed mathematical co-processor. The algorithm is based on non-linear differential correction (also known as the Gauss-Newton method) and uses Doppler and bearing data from a Passive Coherent Location (PCL) radar system. A PCL radar uses a network of receivers to track targets through their back-scatter from existing Continuous Wave (CW) transmissions, such as broadcast TV or radio. The lack of an active transmitter in a PCL system results in relatively low procurement, operation and maintenance costs. This is of particular advantage for airports in third world countries, many of which do not have radar assisted air traffic control.
