Demonstration of multistation/CSP capability for range control

The required accuracy in impact prediction for range control purposes can be achieved only through better velocity estimation. Coherent signal processing (CSP) was developed to provide the C band radars with a Doppler or range rate capability and in a multistation solution to give the required better velocity estimate. Even though various studies tend to show the possibility of substantial improvement through the use of multistation with Doppler solutions, very limited use has been made of multistation solutions for real time range control purposes. A primary purpose of this task was to develop the means for and evaluate the capability of CSP and a range instrumentation system for meeting the IIP requirements of range control. To make the evaluation as complete and definitive as necessary for the purpose, both random and systematic error in IIP were evaluated and for both nominal trajectories and for missile failure cases. Computer programs were developed to facilitate this evaluation.
