Abstract: A radar system and method for maintaining radar performance of radar system in jammed environment are provided. The radar system has main antenna arrangement for transmitting and/or receiving electromagnetic waves. Main antenna arrangement includes at least one main antenna element and at least one main electronics module for transmitting and/or receiving signals to/from at least one main antenna element. The system has auxiliary antenna arrangement for transmitting and/or receiving electromagnetic waves, auxiliary antenna arrangement includes at least one auxiliary antenna element and at least one auxiliary electronics module for transmitting and/or receiving signals to/from the at least one auxiliary antenna element. System has a controller connected to main antenna arrangement and to auxiliary antenna arrangement. Controller is configured to transmit first radar waveform from main antenna element, and transmit second radar waveform from auxiliary antenna element.
