  • Patent number: 12000949
    Abstract: Systems, methods, and computer-readable storage media for generating, transmitting, and utilizing a composite radar and communication waveform are disclosed. The composite radar and communication waveform may facilitate radar detection and data communication operations and may be generated from a frequency modulated (FM) radar waveform and a communication signal. In an aspect, the composite radar and communication waveform may be generated by iteratively executing a shaping process against the FM radar waveform and the communication signal until a first stop criterion is satisfied to produce an initial composite radar and communication waveform having the communication signal embedded therein, and then iteratively executing an enhancement process against the initial composite radar waveform and the communication signal until a second stop criterion is satisfied to produce a final composite radar and communication waveform suitable for both radar detection and data communication operations.

  • Publication number: 20220350009
    Abstract: Systems, methods, and computer-readable storage media for generating and utilizing radar signals with embedded data are disclosed. Data is encoded onto a CPM waveform, which is then combined with a base radar waveform to produce a radar-embedded communication (REC) waveform. Both the CPM waveform and the base radar waveform may have a continuous phase and constant envelope, resulting in the REC waveform having a continuous phase and constant envelope. The changing (e.g., on a pulse-to-pulse basis) nature of the REC waveform causes RSM of clutter which may result in residual clutter after clutter cancellation, decreasing target detection performance of the radar system. In an aspect, various parameters may be utilized to dynamically adjust the performance of the radar system for a particular operating scenario, such as to enhance radar signal processing or enhance data communication capabilities.

  • Publication number: 20210132211
    Abstract: Systems and methods of embodiments provide a feasible approach to implementing Far-Field Radiated Emission Design (FFRED) techniques suitable for simultaneous transmission of radar and communication signals. A set of signals for transmission and a transmission direction for each signal of the set of signals may be determined. The set of signals includes at least a first signal associated with a first transmission direction and a second signal associated with a second transmission direction that is different from the first direction. An optimization problem is configured based on characteristics of an antenna array and the set of signals and then solved to identify a set of waveforms suitable for transmitting the signals. The set of waveforms may include at least two waveforms, each of the at least two waveforms configured for transmission by a different antenna element of the antenna array. The determined waveforms may be coherent in the far-field and suitable for power efficient transmission.
