This article presents the conclusion from my two theses, Comparison of tracking systems and Tracking systems. In the first part with title Comparison of tracking system, was my work focused to research of primary and secondary radar technology with very detailed description and principle of their use. This part of my research consists also from comparison of those two different types of technologies, their advantages and disadvantages. This research was the base stone for my second part of thesis with title: Tracking systems and conclusions, summarized in this article. The second part of thesis is more focused to civil and army passive radar and meteorological technology. The main topic is: how to build up the new radar network by using passive radar technology and what are the advantages and disadvantages of this concept, in comparison with actual primary and secondary radar network. I have chosen Slovak Republic for new network planning but this theory and research is applicable for all the other countries, with some minor changes. This topic is focused mainly to advantages of passive surveillance system and multilateration.
Automotive radar systems using integrated 24 GHz radar sensor techniques are currently under development [1]. This paper describes a radar network consisting of four sensors distributed behind the front bumper of an experimental car. Each single sensor measures the target range with high accuracy. A multilateration technique is used in the radar network for precise azimuth angle estimation even in multiple-target situations. The system performance is shown in real traffic situations for parking aid, stop & go and blind spot applications.
