<p>A radar system having automatic compensation to the heater power applied to the final output tube for changes in the peak tube power output. Substantially constant peak power is attained for radar pulses of varying widths and over a plurality of range scales. A controlled voltage is derived in accordance with the peak of the anode power or current coupled to the final transmitter tube. The control voltage is amplified to operate a free-running bistable multivibrator the output of which is transformer coupled to the heater of the output tube.</p> |
