Abstract :
The results of investigations of 8-mm band FMCW autodyne radar are given in this work. The radar intended for speed and range measurement of objects. Self-detection autodyne transmitter is made on base of Gann diode with varactor tuning. Digital methods of radiating signal forming and spectral signal processing and digital filtering of difference frequency signal are realized in the radar. Autodyne radar potential is not less 85 dB having output power of about 25 mW. Resolution on distance at the tuning band of 500 MHz is 0.6 m and range measurement accuracy 0.3 m. Dimensions of the radar are 92times92times166 mm. Mass is 0.35 Kg.
