Simulating data generated by a network of track-while-scan radars

The echoes generated by single conventional rotating track-while-scan beam radars can be approximately described by a stream of uniformly sampled data. However, the combined stream of a multisite radar network can only be represented by non-uniformly sampled data. To combine several data streams a rigorous calculation of the sampling instants is necessary. The ability to simulate the data produced by a radar network permits to study the performance of tracking algorithms when operating under irregular sampled data. To simulate the radar network we employ the heterogeneous flow system specification (HFSS), a modeling and simulation formalism designed to represent dynamic structure hybrid systems. We present the performance of a α-β filter based on the data obtained through the simulation of a network of three track-while-scanning radars.
