Microwave power transmitter for doppler radar |
摘要 |
In a microwave power transmitter for Doppler radars for terrestrial surveillance, use is made of four stages in series comprising first and second preamplifiers, and first and second power amplifiers. These stages are supplied by a group of separate voltage regulators. These regulators are controlled by a control circuit which makes it possible to cut off the stabilized voltage between instants of transmission, that is to say between microwave pulses of a radar signal. A feedback device makes it possible to stabilize the output level by causing variation of the gain of the first preamplifier by means of its supply voltage.
