Parkedcar_tgt = phased.RadarTarget( 'PropagationSpeed',c, 'OperatingFrequency',fc, 'MeanRCS',10)

Parkedcar = phased.Platform( 'InitialPosition',parkedcar_pos, 'Velocity',parkedcar_vel. Specify the location of the helicopter as (500, 0, 500), which sets its distance away from the radar in meters and a velocity of (60, 0, 0) m/s.Įgocar = phased.Platform( 'InitialPosition',egocar_pos, 'Velocity',egocar_vel. Assume the radar is located at the origin. Estimating Blade Speed of A HelicopterĬonsider a helicopter with four rotor blades. In the second application, the micro-Doppler signatures are used to identify a pedestrian in an automotive radar return. In the first application, micro-Doppler signatures are used to determine the blade speed of a helicopter. This example shows two applications where micro-Doppler effects can be helpful. These micro scale movements produce additional Doppler shifts, referred to as micro-Doppler effects, which are useful in identifying target features. For example, when a helicopter flies, its blades rotate, or when a person walks, their arms swing naturally. However, because most targets are not rigid bodies, there are often other vibrations and rotations in different parts of the target in addition to the platform movement. A moving target introduces a frequency shift in the radar return due to Doppler effect.
