PURPOSE:To realize a miniature and inexpensive device by providing one device with the fluctions of a pulse radar and CW radar. CONSTITUTION:The output of high-frequency oscillator 12 is applied to antenna 15 via switching circuit 13 and high frequency amplifier 14, and a pulse wave and CW wave are sent out by turns according to a repectitive signal outptted from pulse/CW controller 11. A reflected wave from a target is detected by detector 23 by way of antenna 16, high-frequency amplifier 17, mixer 18, and intermediate- frequency amplifier 22 and then inputted to display device 24, and it is also processed by filter group 25, detector group 26 and matrix circuit 27 and then inputted to display device 24. On display device 24, distance information on the target and speed information are displayed simultaneously. |
