A synthetic aperture radar method for remote sensing of the Earth's surface (GR) via a multi-aperture radar system on a platform moving in an azimuthal direction (x) above the Earth's surface (GR), wherein the multi-aperture radar system includes a combined transmitting and receiving device , which is a transmitting device in the transmission mode, which emits radar pulses (RP), and which is a receiving device in the receiving mode, which receives radar echoes (EC) of these radar pulses (RP) reflected off the earth's surface (GR) by way of several receiving channels (RC1, RC2, RC3, RC4) with associated receivers, wherein the receivers of the receiving channels (RC1, RC2, RC3, RC4) are disposed on the platform, so that they are offset relative to each other in the azimuth direction (x), wherein an antenna diagram with a phase center (PC) at an azimuth position (x) in the azimuth direction is associated with a respective receiving channel (RC1, RC2, RC3, RC4) for each radar echo (EC) received through it, coming from the same range position in a range direction (y), wherein the range direction (y) runs along the surface of the earth (GR) perpendicularly to the azimuth direction (x), wherein: - radar pulses (RP) are transmitted by the transmitting device at successive transmission times, wherein the time intervals (PRI 0 , PRI 1 , PRI 2 , PRI n ) vary at least sometimes between successive transmission times; - the radar echoes of the radar pulses (RP) are received by the receiving device via the respective receiving channels (RC1, RC2, RC3, RC4), whereby, for the radar echoes (EC) originating from the same range position (y), first samples (a1) are obtained for this range position, each corresponding to a receiving channel (RC1, RC2, RC3, RC4) for a received radar echo (EC), wherein a respective first sample (a1) is associated with the phase center (PC) of the antenna diagram of the corresponding receiving channel (RC1, RC2, RC3, RC4) for the received radar echo (EC); characterized in that the first samples (a1) for the same range position are converted into second samples for that range position, by determining a respective second sample (a2) from the first samples (a1) in a receive sequence (RS) of several radar echoes (EC) which are successively received in the receiving device, in such a manner that the antenna diagrams of all receiving channels (RC1, RC2, RC3, RC4) are weighted and combined for all radar echoes (EC) of the receive sequence (RS) based on one or several optimization targets, wherein the or one of the optimization targets is a predetermined uniform local distance between the phase centers (PC') of the second samples (a2). - radar pulses (RP) are transmitted by the transmitting device at successive transmission times, wherein the time intervals (PRI 0 , PRI 1 , PRI 2 , PRI n ) vary at least sometimes between successive transmission times; - the radar echoes of the radar pulses (RP) are received by the receiving device via the respective receiving channels (RC1, RC2, RC3, RC4), whereby, for the radar echoes (EC) originating from the same range position (y), first samples (a1) are obtained for this range position, each corresponding to a receiving channel (RC1, RC2, RC3, RC4) for a received radar echo (EC), wherein a respective first sample (a1) is associated with the phase center (PC) of the antenna diagram of the corresponding receiving channel (RC1, RC2, RC3, RC4) for the received radar echo (EC); <EOS>
