SOLID STATE BI-DIRECTIONAL MICROWAVE REPEATER FOR GUIDED RADAR OBSTACLE DETECTION IN GROUND TRANSPORTATION

The design and fabrication of a bi-directional microwave repeater amplifier incorporating two single stage microwave transistor amplifiers (at 1 GHz) is presented in this work. Limitations of the repeater due to mismatches at the input and output ports are described. Circuits similar to Echo Suppressors and Echo Cancellers used in two-wire telephone systems are suggested for the reduction of the effects of mismatches at the two ports of the repeater.
