An antenna in a given direction, 4π times the ratio of the radiation intensity in that direction to the total power radiated by the antenna.
The Crossed Field Amplifier is a microwave power amplifier based on the magnetron and looking very much like it. It is a cross between the TWT and the magnetron in…
difference between the target direction and the reference direction The tracking radar attempts to position the antenna with zero angular error
The pulse width (H) determines the minimum range at which targets can be detected. This minimum range is approximately ½ the length of the wave burst
The empty weight mass fraction is the ratio of the empty weight (WEmpty) to Takeoff gross weight (WTO)
