The design process consisted of computer design by circuit simulation software integrate with electromagnetic simulation software, fabrication of microstrip bpf 、 lpf 、 the match circuits, cavity and test. when rf frequency is 91 ~ 97ghz, lo frequency is 47ghz, power is 10 dbm. the best conversion loss of the 2 and 4 sub - harmonic mixer is 13. 5 db and 23. 5db which is shown in the test
實測表明，在本振為47ghz ，功率10dbm ，測試射頻帶寬為91ghz 97ghz時，二次與四次分諧波混頻器變頻損耗最優處分別為12 . 7db和23db 。最後對實驗結果進行分析並提出改進措施。 -
Measured result shows that the doppler radar signal we get in the self - oscillating mixer based doppler radar is about 400hz which matches well with the velocity of a moving object. the best conversion loss in fmcw system measures - 10db which is similar to the simulated result
通過對自振混頻技術在多普勒雷達中應用的測試，得到多普勒回波信號的頻率為400hz ，運動速度可以計算為6m / s ，與實際物體的運動速度相吻合。
