This report studies, on a general basis, whether wind farms may decrease the accuracy of direction finding systems in the HF (high frequency, 2-30 MHz) band, due to scattering from

Since the position of the target can be known even when it is moving, the beam pattern can thus be removed from the measurement, allowing direct sensing of

In the absence of measurements, the phase function for the EK-50 ecko sounder was assumed to be identica1 to that Q £ the EK-38 after appropriate frequency-shifting.. The

6.1 Traynor, J. Target strength measurements of walleye pollack Theragra chalcogramma and whiting Merluccius productus. This paper repots on recent target strength

The target strength of herring for each sub-area was calculated from the mean length frequency distribution using the formula recommended by the ·Acoustic

Manual scrutiny of the acoustic data for the scientific survey suggested that the majority of events with stronger scatter at 38 kHz than at 120 kHz were caused by animals with

For the actual meeting, the agreed process rules were that: (1) Additional evidence would only be allowed at the meeting if it had been omitted from the evidence summaries, or

The maximum temperature at the surface for a stable atmosphere would be if it followed the adiabatic lapse rate from the known temperature point (if it were higher, convective
