Abstract
The frequency of a variable frequency oscillator in a pulsed radar is adjusted using samples of an IF signal. An initial frequency adjustment is made using a sample taken during RF transmission. This initial adjustment contains an inaccuracy introduced by the magnetron's activity. An additional adjustment is made using temperature dependent values stored in a memory. Yet another adjustment is made during the radar's receive time using signals reflected by targets.
