Abstract: The invention relates to a process for the evaluating a received signal of an SAR/MTI pulsed radar system that transmits SAR and MTI pulses with respective definable pulse repetition frequency PRF_SAR and PRF_MTI, such that the received signal is a superimposition consisting of echo pulse sequences of SAR and MTI echo pulse signals. According to the invention, in the received echo pulse sequence of the received signal, each SAR echo from an area of interest is evaluated SAR process. The remaining pulses of the received echo pulse sequence of the received signal are evaluated in using an MTI process.

Abstract: In an aircraft on-board radar arrangement including a search radar and a radar warning receiving system, an additional receiving branch is provided to which are fed foreign radar signals received by the sharply focused transmit/receive antenna of the search radar, with the output of the additional receiving branch being connected to the radar warning receiver. This results in a greater angular resolution and a considerable increase in range, which again leads to a more detailed and early detected of threatening situations. By using already available components and because of the simple configuration of the additional receiving branch, additional costs remain low.
