A pulse-echo ranging system is described employing a microwave transducer head (100) providing an echo profile output signal which is largely compatible with receivers (204) and echo processing systems (206) designed for acoustic transducers. The transducer head employs novel microwave pulse generators (20a, 20b) each utilizing a microwave cavity (20a 20b) excited by an , avalanche discharge through a small signal diode (D2a D2b) initiated by , avalanche of a driver transistor (TR1a TR1b) by a trigger pulse. Repeated , pulses from one generator (2a) are transmitted by an antenna (12) towards a target, and return are mixed with pulses from the second generator (26) which are subject to …
