Phase-Modulated Radar Detection With Receiver-Side Phase Control

The patent segments the radar system into a single transmitter and multiple receivers, where each receiver is equipped with phase control elements. This segmentation allows the system to achieve MIMO-like angle resolution by processing signals from multiple receivers with different phase configurations, while avoiding the complexity of multiple transmitters. The phase control elements at each receiver enable independent phase manipulation, creating virtual antenna arrays through software control rather than physical multiplication of transmitter components.

The patent changes the phase parameter of received signals using phase control elements at each receiver. By dynamically adjusting phase shifts across multiple receivers, the system creates different virtual beamforming configurations without adding physical transmitters. This parameter-based approach allows the system to synthesize multiple transmit-receive channels through phase modulation, achieving high angle resolution while maintaining simpler hardware architecture.

The system segments the detection function across multiple receivers with phase control elements, where each receiver independently processes signals with configurable phase shifts. This segmentation enables diverse signal processing paths and virtual array configurations that enhance detection reliability through multiple observation angles, while avoiding the hardware complexity of multiple transmitters by concentrating phase control at the receiver side.

The phase control elements at each receiver provide multi-functionality, enabling the same hardware configuration to perform multiple detection tasks by changing phase settings. The receivers can dynamically reconfigure their phase patterns to adapt to different detection scenarios, target positions, and resolution requirements, making the system universally applicable while maintaining hardware simplicity.
