Intelligence Surveillance Reconnaissance Airship Drone with Radio Relay (ISRADRR)

ISRADRR team location

- unmanned aerial vehicle up to an altitude of 5,500 m, up to 20 days of continuous flight operation mainly in geostationary position, provision of line-of-sight radio signals according to IEEE 802.11 (Wi-Fi), HF / VHF / UHF, real-time imaging (still image, video, thermography) and data transmission, computer vision and object recognition, radar detection and target designation station with active phase antenna, LiDAR and ultrasonic sensors for surface scanning, confocal diffuse tomography through clouds.

For supporting various tactical operations our development can play a great role - Intelligence Surveillance Reconnaissance Airship Drone with Radio Relay (ISRADR), an aerostatically unloaded drone operating at 900-5500 m altitude, carrying a payload of equipment for tropospheric communications in VHF/UHF band, transverters for radio wave frequency conversion as well as independent radio-relay and radar equipment (active and passive radars). The main advantage is cost effectiveness and energy efficiency, long continuous operation time with maintenance of geostationary position, capability of quick evasion and sophisticated maneuvering in case of threats, low cost in comparison with any other types of airborne radars. It is important to mention it here because in this way inexpensive stable communication channels are formed for ARHUDFM users not only beyond line of sight, but also long-range communication channels of tens of thousands of kilometers.

Tasks of convoy escort and tactical support within a radius of tens of miles. Designed to operate in a group of three or more units as a communications node using a wide range of radio frequencies, as a local weather station, monitoring for optical, infrared, thermal, and radar detection with recognition and targeting functions, and for continuous tracking of objects and movements, radio signal sources, and firing points, elevation angles of artillery pieces and launchers, smoke and heat trails of rocket engines, low-flying aircraft and ground drones, for calculating ballistic trajectories (own and enemy) and fire corrections based on artificial intelligence algorithms, for comparing map material with detection of changes in technical communications and structures therein. The reactions of radar warning systems are not triggered.

Protection: optical, acoustic, and infrared line-of-sight obstruction, hampered radio direction finding, radar or laser threat assessment, electronic defense and laser radar defense (decoys and traps), radio complex modulated retransmission of radar sounding signals, radio missile fuse interference and electromagnetic pulse interference, sophisticated spiral evasive maneuver, and passive receive mode before changing position.
