The present invention relates to a method for detecting targets, which is used by a multifunction radar. The radar comprises an antenna subdivided into at least two portions and is configured such as to transmit at least two types of signals over different frequency bands and to carry out at least one function of ground detection or imaging. During the phases of transmission of an antenna portion, the reception of each antenna portion of the radar is cut off. According to the invention, the method comprises, for each range gate, a step of receiving signals, a step of estimating the autocorrelation matrix associated with the interferences of the ground returns and of the thermal noise of the radar, and a step of target detection by means of a generalized maximum likelihood test. The invention further relates to a multifunction radar configured such as to implement the method for detecting targets. |
