Passive Geolocation for Multiple Receivers With No Initial State Estimate

Abstract

In his book Electronic Intelligence: the Analysis of Radar Signals, author Richard Wiley analyses a triangulation scenario for two stationary receivers with one stationary emitter using bearings-only knowledge. In this report his work is extended to the case of more receivers using a least squares approach. DSTO describes how this is done, plotting results for some representative scenarios as well as extending the work to the moving emitter case. The result is that accurate geolocation estimates can be produced with some very compact computer code, especially when taking advantage of modern fast techniques for numerical computations.
