ABSTRACT:
Device for radar utilized to detect multiple-time-around echoes with the capability of transmitting in frequency agility and, besides the advantages due to this type of technique, further, capable of reading the ambiguity of distance directly by separating in frequency the multiple-time-around echoes. The device described is applicable to any pulses radar, such as for example, search or tracking, in which it is necessary to detect targets and recognize multiple-time-around echoes. Nevertheless its application is especially suited to a multifunctional radar (with phased-array antenna and monopulse capability).
