Abstract:
Modern warfare is carried out in a complex electromagnetic environment, where noise suppression interference
directly affects the detection ability of airborne warning radar to target, in order to make airborne warning radar play its due role
in battlefield. More and more requirements are put forward for radar combat capability in complex electromagnetic environment,
that is, the requirement of radar anti-jamming ability in complex electromagnetic environment is becoming higher and higher.
Suppression jamming is to cover or submerge useful signals with noise or similar jamming signals to prevent radar from
detecting target signals. In order to evaluate the influence of suppression jamming on airborne warning radar, the influence of
suppression jamming on the detection probability and detection distance of warning radar is analyzed. The variation of radar
detection range and detection probability in complex electromagnetic environment compared with normal detection is given by
flight test. It also provides a reference for evaluating the anti-jamming ability of airborne warning radar after being suppressed.
