An Airborne/Spaceborne Distributed Aperture Multi Sensing RF Pulsed System comprising one or more Radiating Groups, and a Central Control Processing Unit configured to cause the Radiating Groups to independently and selectively perform the same or different pulsed RF functions among Radar, Communication, Electronic Warfare, Data-Link, Interrogator Friend or Foe; each Radiating Group comprises a basic Transmit-Receive Module, where transmit and receive functions are separated, and comprising: - a Transmit-only Antenna Module comprising a phased array of transmit-only antenna elements, - a Receive-only Antenna Module comprising a phased array of receive-only antenna elements, and - an Antenna Controller configured to cause the transmit-only antenna elements in the Transmit-only Antenna Module to transmit an RF beam having a transmit pattern with a transmit beamwidth, and the receive-only antenna elements in the Receive-only Antenna Module to receive multiple simultaneous RF beams processable to generate receive beams having receive patterns with receive beamwidths individually narrower than transmit beamwidth; the Antenna Controller is further configured to cause the Transmit-only Antenna Module and the Receive-only Antenna Module to independently and selectively perform the same or different ones of the pulsed RF functions; the number of transmit-only antenna elements in the Transmit-only Antenna Module is lower than the number of receive-only antenna elements in the Receive-only Antenna Module, the Transmit-only Antenna Module and the Receive-only Antenna Module are designed such that the transmit beam has a lower directivity than the individual receive beams so as to result in the transmit beam having a wider azimuthal and/or elevational beamwidth than the individual receive beams, and the Transmit-only Antenna Module has an antenna gain lower than the Receive-only Antenna Module; each Radiating Group further comprises an additional Transmit-Receive Module, operatively independent from the basic Transmit-Receive Module, and where transmit and receive functions are not separated; the additional Transmit-Receive Module comprises: - a Transmit and Receive Antenna Module comprising a phased array of transmitting and receiving antenna elements, wherein the number of antenna elements in the additional Transmit-Receive Module is lower than the number of antenna elements in the Receive-only Antenna Module; and - an Antenna Controller; the Antenna Controllers ( 11, 16) of the basic Transmit-Receive Module and of the additional Transmit-Receive Module are designed to cause the basic Transmit-Receive Module and the additional Transmit-Receive Module to independently and selectively perform the same or different ones of the pulsed RF functions. - a Transmit-only Antenna Module comprising a phased array of transmit-only antenna elements, - a Receive-only Antenna Module comprising a phased array of receive-only antenna elements, and - an Antenna Controller configured to cause the transmit-only antenna elements in the Transmit-only Antenna Module to transmit an RF beam having a transmit pattern with a transmit beamwidth, and the receive-only antenna elements in the Receive-only Antenna Module to receive multiple simultaneous RF beams processable to generate receive beams having receive patterns with receive beamwidths individually narrower than transmit beamwidth; - a Transmit and Receive Antenna Module comprising a phased array of transmitting and receiving antenna elements, wherein the number of antenna elements in the additional Transmit-Receive Module is lower than the number of antenna elements in the Receive-only Antenna Module; and - an Antenna Controller;
