A micro-Doppler simulation scenario using a monostatic radar and four-blade helicopter [90]. The monostatic radar is immovable and is placed at the origin. The initial helicopter coordinates are (700,0,700). The blades of the helicopter rotate at four revolutions per second, and the velocity of the helicopter is 80 m/s.
