Abstract
A novel radar modelling Framework and its associated innovative modelling techniques are described. The Framework provides generic techniques for modelling a wide variety of radars, radar environments and scenarios, using a flexible object-oriented approach. It addresses many of the shortfalls of current radar models and provides a foundation for efficient radar model developments in the longer term. The history of radar modelling is briefly described and current commercially available radar modelling packages are evaluated. Having determined the need for a more generic modelling approach, the objectives for the Framework (modular, hierarchical, reusable) are established. The basic Framework principles are determined by reference to the radar equation. The Framework decomposes a radar model into component blocks, at a level that gives flexibility without requiring an excessively deep hierarchy of blocks. The Framework defines the special data bus structure used to link blocks to form a radar simulation. A review of simulation acceleration techniques leads to the novel concept of Mixed Mode Modelling, wherein parts of a radar model can be simulated to differing levels of detail, to optimise simulation performance without unduly compromising accuracy. The Framework is applied to the simulation of a multifunction radar to evaluate and prove the Framework principles. This simulation is adapted to use Mixed Mode Modelling to determine its performance benefits. The simulation is further enhanced to create a detailed model of a naval phased array radar which is exercised using various engagement scenarios. This model is intended to aid in defining key design details such as signal processing and energy management strategies. Results from these radar models are used to confirm and support the generic radar modelling techniques presented. Conclusions are drawn as to the value of the Framework for future radar modelling programmes and potential areas for future development and enhancement are identified.
