<p><P>PROBLEM TO BE SOLVED: To accurately obtain an angle with an angle measurement radar operating the angle of a detecting object direction based on two antenna reception strengths. <P>SOLUTION: A transmission beam is radiated from a transmission antenna 4 and a reflection beam from a detecting object with two reception antennas 5a and 5b. The reception beam is inputted to a signal processor 14 by way of an FM-CW transmitter/receiver 7 and an A/D convertor 8. Reception beam intensity is corrected in an antenna gain difference corrector 18 with the data of gain difference of the reception antennas 5a and 5b inputted by a reception reference signal memory 17. The corrected reception beam is analyzed for frequency by a FFT processor 19, and a beam intensity over a specific threshold is extracted in a CFAR processor 20 as a component from the detecting object. An environmental noise corrector 21 subtracts the beam intensity around the frequency as a noise component from the extracted beam intensity. <P>COPYRIGHT: (C)2003,JPO</p> |
