Definitions

  • the present disclosure relates to methods and systems for automatically measuring and/or obtaining parameters from systems and/or antennas, in particular for determining the directions of incidence of electromagnetic waves, in particular direction finding systems and/or direction finding antennas, using a transmission device on an unmanned aircraft is arranged.
  • Direction-finding antennas for determining the direction of incidence of electromagnetic waves can have direction-finding errors due to environmental influences.
  • DF antennas for mobile platforms are required for very wide frequency ranges. Due to the compact design, frequency-dependent coupling of the direction-finding antenna with the platform can occur and thus influence the direction-finding accuracy. In the case of stationary DF antennas under real conditions, DF errors can also occur due to environmental inhomogeneities.
  • the DF antenna is measured perimetrically around 360° using conventional methods with a transmitter system, for practical reasons circular, equidistant target angles.
  • the error curve and the resulting correction curve can be obtained. These measurements can be carried out per azimuth for all frequencies with the aid of tunable transmission equipment. This set of measured values is part of the DF antenna and is used to correct the DF values during DF operation.
  • the transmission device is transported to the target angle locations.
  • the DF antenna can be attached to a rotating device, the antenna is rotated to the desired angle and the measurement can be carried out using a stationary transmitter.
  • This is usually the case with smaller, more compact DF antennas VHF frequency range and higher is possible and is used in particular for preliminary measurements before the antennas are installed on high masts or on mobile platforms.
  • the finally installed DF antennas are often difficult to measure on site due to poor accessibility, terrain problems, etc. or due to weight and dimension problems of the platform.
  • the measurement is then carried out by changing the location of the transmitting device in the real environment to the respective target angle.
  • These measurements are very time consuming and expensive. This often leads to unsuitable transmission locations combined with location-dependent propagation conditions due to the environmental and earth inhomogeneities and reflectors. This results in additional measurement errors, which are noticeable as further bearing errors and cannot be detected.
  • These effects are primarily caused by the possibility of mounting the transmitting antenna of the transmitting device at a relatively low height or only on the ground and thus by unwanted, location-dependent reflections of the real environment and by the different influence of the inhomogeneities mentioned when changing location on a different target angle of the transmitter.
  • US 2019/0331800 A1 relates to the testing of directional antennas, such as COTM ("Communication-On-The-Move") antennas.
  • COTM Common-On-The-Move
  • the central problem here is that the directional antenna must constantly be precisely aligned with the satellite in order not to lose communication.
  • the problem particularly affects directional antennas with mechanical drives. These drives ensure that the antenna is constantly rotated in the direction of the satellite beam as the platform moves. With aging and wear and tear of the drive mechanism, impermissible deviations from the target direction to the satellite beam occur, which can lead to the loss of communication.
  • the readjustment - especially on ship platforms and the like. - is associated with many problems and a lot of effort.
  • the drone simulates the satellite by sending useful or tracking signals and then the measurements specific to directional antennas are carried

  • US 2019/0331800 A1 does not describe a method for automatically measuring and/or obtaining parameters of direction finding systems and/or direction finding antennas for determining the directions of incidence of electromagnetic waves and the corresponding determination of radio loading values
  • direction finding antennas are multidirectional and frequency-wise very broadband antennas and react much more sensitively to the environment than directionally selective antennas. It is therefore necessary to generate a large number of correction tables with parameters such as azimuth and a very fine frequency step. For example, will When measuring a VHF/UHF interferometer direction finding antenna system for the frequency range 20-3000 MHz, hundreds of error curves were recorded at frequency steps of 10 MHz, with the entire circle of 360° being measured at each frequency with angular steps of 10°, for example.
