Syntax

Y = reflect(pedestrian,X,ANG)

Description

Y= reflect(pedestrian,X,ANG)returns the reflected signal,Y, from incident signals,X, on a pedestrian. The reflected signal is the sum of signals from all body segments.ANGdefines the directions of the incident and reflected signals with respect to the body segments.

Input Arguments

collapse all

Pedestrian target model, specified as abackscatterPedestrianobject.

Incident radar signals on each body segment, specified as a complex-valuedM-by-16 matrix.Mis the number of samples in the signal. SeeBody Segment Indicesfor the column representing the incident signal at each body segment.

Data Types:double
Complex Number Support:Yes

Directions of incident signals on the body segments, specified as a real-valued 2-by-16 matrix. Each column ofANGspecifies the incident direction of the signal to the corresponding body part. Each column takes the form of an azimuth-elevation pair,[AzimuthAngle;ElevationAngle]. Units are in degrees. SeeBody Segment Indicesfor the column representing the incident direction at each body segment.

Data Types:double

Output Arguments

collapse all

Combined reflected radar signals, returned as a complex-valuedM-by-1 column vector.Mequals the same number of samples as in the input signal,X.

Data Types:double
Complex Number Support:Yes

Body Segment Indices

Body segment indices define which columns inXandANGcontain the data for a specific body segment. For example, column 3 ofXcontains sample data for the left lower leg. Column 3 ofANGcontains the arrival angle of the signal at the left lower leg.
