Phased Array System Toolbox / Detection
The Range Estimator block estimates the range of target detections obtained from the radar response data.
Resp — Range-processed response data cube
complex-valued P-by-1 column vector | complex-valued M-by-P matrix | complex-valued M-by-N-by-P matrix
Range-processed response data cube, specified as a complex-valued P-by-1 column vector, a complex-valued M-by-P matrix, or a complex-valued M-by-N-by-P array. M represents the number of range samples, N is the number of sensor elements or beams, and P is the number of Doppler bins.
The size of the first dimension of the input matrix can vary to simulate a changing signal length. A size change can occur, for example, in the case of a pulse waveform with variable pulse repetition frequency.
Complex Number Support: Yes
Range — Range grid values along range dimension
real-valued M-by-1 column vector
Range grid values along the range dimension of the data cube input, Resp, specified as a real-valued M-by-1 column vector. Range values must be monotonically increasing and equally spaced. Units are in meters.
Est — Range estimate
real-valued K-by-1 column vector
Range estimates, specified as a real-valued K-by-1 column vector.
When Enable cluster ID input is not selected, each range estimate corresponds to one of the columns of the DetIdx input port. Then K equals the column dimension, Q, of DetIdx.
When Enable cluster ID input is selected, each range estimate corresponds to one of the cluster IDs in the Clusters input port. Then K equals the number of unique cluster IDs.
Var — Range estimation variance
positive, real-valued K-by-1 column vector
Range estimation variance, returned as a positive, real-valued K-by-1 column vector, where K is the dimension of Est. Each element of Var corresponds to an element of Est. The estimator variance is computed using the Ziv-Zakai bound.
To enable this output port, select the Output variance for parameter estimates parameter.
Root-mean-square range resolution — Range resolution
2 (default) | positive scalar
Root-mean-square range resolution of the detection, specified as a positive scalar. This parameter must have the same units as the Range input port.
To enable this parameter, select the
for parameter estimates parameter.
