PURPOSE:To eliminate a skip of reception by polarizing transmitted pulses differently. CONSTITUTION:The signal generator of a transmitter 5 generates frequency- modulated transmit pulses of different frequencies f1 and f2 among transmit pulses and the polarization switch (a) of an antenna 1 performs polarization differently among the transmit pulses according to the modulation frequencies f1 and f2. Therefore, even if one polarized wave is disturbed, reception is carried out with the other polarized wave and the reception of every other transmit pulse is eliminated, thereby receiving at every transmit pulse is executed. |
