ABSTRACT:
Radar apparatus and method for eliminating ambiguity in radar range measurements. The radar emits bursts of n pulses and the emission frequency is changed at each new burst. The number M of pulses received after reflection from a target is counted. If N is the number of pulses emitted when a target is within the scanning space of the radar, the number M is compared with numbers N, N(n-1)
, . . . N(n-i)
, . . . , N
. The result of the comparison is used for classifying the echoes received in their respective recurrence up to the n.sup.th recurrence. The echoes can be readily identified since the emission frequencies of adjacent bursts are different. Thus, the useful range of the radar is increased without increasing the recurrence period of the pulses emitted.
