Method of operating a radar according to a synthetic aperture imaging mode and a second operating mode using random phases and associated radar

Abstract

A method of operating a target detection radar following a first mode of operation and at least one second mode of operation, the first mode of operation being a synthetic aperture radar imaging mode and each second mode of operation being different from the first mode of operation, the method including the implementation of several recurrences of a signal emission/reception operation, wherein, for each N, the Nth recurrence of the operation including the following sub-operations: generation of a sequence of consecutive pulses, each pulse of the sequence being associated with a respective mode of operation, emission of the pulses in different frequency bands, and reception of the pulse echoes in a common time window, during the sub-operation of emission, at least one of the pulses, called the out of phase pulse, being emitted with a random phase associated with the number N.
