| 41. | Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength.
|
| 42. | Although the reflected radar signals captured by the receiving antenna are usually very weak, they can be strengthened by electronic amplifiers.
|
| 43. | In a receiving antenna it transfers the tiny RF voltage induced in the antenna by the radio wave to the receiver.
|
| 44. | According to reciprocity, the efficiency of an antenna used as a receiving antenna is identical to the efficiency as defined above.
|
| 45. | Atmospheric noise and not receiver noise determines the receiver signal to noise ratio, so small inefficient receiving antennas can be used.
|
| 46. | By adjusting the receiving antenna for one or the other polarization, either signal can be selected without interference from the other.
|
| 47. | There are to be T time slots and n _ T transmit antennas as well as n _ R receive antennas.
|
| 48. | Especially at microwave frequencies, a receiving antenna may include not only the actual electrical antenna but an integrated preamplifier or mixer.
|
| 49. | The mission officially ends on Wednesday and there are no plans for deep-space receiving antennas to monitor the craft after that.
|
| 50. | The directional arguments are now relative to the receiving antenna, and again A is taken to include ohmic and mismatch losses.
