A method to infer height information from an aircraft tracked with a single 2-D search radar is presented. The method assumes level flight in the target aircraft and a good estimate of the speed of the aircraft. The method yields good results for medium to high altitudes, though performs weaker at low altitudes. The method can distinguish between high and low targets on a normal 2-D radar, and can reach a height resolution of 100 m provided the 2-D radar is optimised to the task.

INTRODUCTIONThis chapter briefly outlines a few mathematical techniques to track targets in 3D using a 2D radar. 2D radars are relatively cheap and efficient sensors that often form the first line of defence in airspace control. In military applications they are often used as early-warning devices because they can detect approaching enemy aircraft or missiles at great distances. In case of an attack, early detection of the enemy is vital for a successful defence against attack. Depending on the threat evaluation of tracked aircraft the tracking process is passed along to 3D search radars or fire control tracking radars once it comes into range of those sensors. A key component in the above hierarchy is the threat evaluation component. It relies on many factors such as angle of incidence towards defended assets, time to approach to defended asset, speed of target and so forth. The normal 2D radar provides range and azimuth but the altitude of the target is omitted. This can be an important consideration as aircraft altitude limits the attack profiles a target can fly [1].

“…Hence, the determined flight path of the entity can be readily compared with manoeuvre profiles 2 and a good measure can be obtained for its projected future trajectory as well as offering a strong basis for threat evaluation.…”

Understanding airspace activity is essential for airspace control. Being able to detect vertical activity in aircraft allows prediction of aircraft intent, thereby allowing more accurate situation awareness and correspondingly more appropriate airspace control response. The method for qualitative vertical activity estimation as presented is characterised by a very fast response time and requires minimal sensor input. The method relies on the interplay of two opposing motion prediction models. The efficacy of the method is demonstrated in both simulated and real-world data.
