Duplex JCAS Operator¶

class DuplexJCASOperator(waveform=None, selected_transmit_ports=None, selected_receive_ports=None, carrier_frequency=None, seed=None)[source]¶

Bases: Generic[CWT], RadarBase[JCASTransmission, JCASReception], TransmittingModemBase[CWT], ReceivingModemBase[CWT]

Base class for duplex joint communication and sensing operators.

Duplex joint communication and sensing operators transmit a modulated waveform while simultaneously deriving a radar cube from the received backscattered power.

Parameters:

waveform (CWT, optional) – Communication waveform emitted by this operator.
selected_transmit_ports (Sequence[int] | None) – Indices of antenna ports selected for transmission from the operated Device's antenna array. If not specified, all available ports will be considered.
selected_receive_ports (Sequence[int] | None) – Indices of antenna ports selected for reception from the operated Device's antenna array. If not specified, all available antenna ports will be considered.
carrier_frequency (float, optional) – Central frequency of the mixed signal in radio-frequency transmission band. If not specified, the operated device’s default carrier frequency will be assumed during signal processing.
seed (int, optional) – Random seed used to initialize the pseudo-random number generator.

property frame_duration: float¶

Duration of a single sample frame in seconds.

Denoted as \(T_{\mathrm{F}}\) of unit \(\left[ T_{\mathrm{F}} \right] = \mathrm{s}\) in literature.

property sampling_rate: float¶

The operator’s preferred sampling rate in Hz.

Denoted as \(f_{\mathrm{S}}\) of unit \(\left[ f_{\mathrm{S}} \right] = \mathrm{Hz} = \tfrac{1}{\mathrm{s}}\) in literature.
