A radar imaging device having a mission to produce a radar image of a given target, comprising a step of determining the trajectory of the carrier of the imaging device comprises at least: a phase of determining a segment of trajectory for the picture capture, as a function of the position of the target and of the type of image to be produced, the picture capture segment being dedicated to the picture capture of the target by the imaging device; a phase of adding a segment of trajectory of stabilizing the carrier, situated upstream in the extension of the picture capture segment; a phase of addition of a segment of trajectory for homing the carrier onto the stabilizing segment.

Method of optimizing picture captures carried out by an airborne radar imaging device, and mission system implementing such a method

A detection method for a given mission comprises at least: one phase of analysing the environment using a waveform chosen beforehand, the signals acquired with this waveform being analysed by processing means in order to deduce therefrom environmental characteristics; and one phase of generating an optimal detection wave depending on the environmental characteristics and characteristics of the mission.

Method for optimising the detection of marine targets and radar implementing such a method

A detection method for a given mission comprises: a phase of analyzing the environment, wherein phase elements of influence on the sea clutter perceived by the radar are sought and stored in memory; a phase of updating the path to be followed by the carrier depending on the requirements of the mission and the elements of influence issued from the result of the analyzing phase, the path to be followed decreasing the power of the clutter received by the radar when the antenna is pointing towards a search zone liable to contain a target; the phases being repeated throughout the mission.
