AbstractThe RCAF considers chaff to be one of the main threats in an air attack because of the presentation of a large number of false alarms to a PPI operator or to the automatic data transmission equipment (the AN/FST-2). Normally, MTI is not effective because the radial velocity of the chaff lies outside the blind speeds (velocity notches). In a fully coherent radar, such as the NA/FPS-508, it is a simple matter to fit a variable-frequency oscillator to shift the velocity notches to cover the chaff's velocity. The design and evaluation of a Variable Velocity Notch Moving Target Indication (VVNMTI) system is described. A more sophisticated design is proposed which will reduce the number of true targets lost owing to the velocity notches.
