ABSTRACT:
This invention discloses pulse radar apparatus for the transmission of radar pulses having a pair of frequencies in each rf pulse. One of the frequencies transmitted in each pulse is repeated in the succeeding pulse while the other frequency is changed to a new frequency. Moreover, the repeated frequency appears in the same relative position in the pulse pair as in its original occurrence.
