The report depicts technical and organizational possibilities with an aim to increase situational
awareness and sea travel safety on the entry to Polish seaports on the base of the dedicated radar system on the
aerostat platform. The radar system based on the aerostat can work at the altitude of 3,000 meters, which allows
detecting sea vessels and low level flying aircrafts in the range of 150 nm and more. The aerostat based in
Siemirowice gives opportunities to monitor movements of sea vessels all over the South Baltic Sea, starting with
the Lithuanian seaside with Klaipeda seaport in the east where the sea enters Zatoka Gdańska and Trójmiasto
seaports, movements along the whole Polish seaside up to Sund Straid near Copenhagen and sea routes all
along south Swedish coast. On those bases, it is possible to observe movements of sea transports of special
interest including Maersk’s big container vessels and gas delivering vessels to Lithuania and to Świnoujście.
The proposed radar system is using solutions of towed aerostats tested in working conditions which are
exploited by the United States of America to monitor its border with Mexico and to observe movements of sea
vessels and low flying aircrafts around Florida Peninsula and Puerto Rico islands on the Caribbean. The radar
systems used by the USA are depicted with organizational rules of their exploitation. Advantages and these
advantages of such a radar system were depicted and some information about dangers related to aerostat’s
exploitation is also provided. Additional possibilities of using the radar system based on the aerostat are
depicted in the role of a new and important part of the country’s defense system.
