RADAR APPARATUS AND TRANSMISSION METHOD OF RADAR APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18611434 titled 'RADAR APPARATUS AND TRANSMISSION METHOD OF RADAR APPARATUS

The radar apparatus described in the abstract consists of multiple transmission antennas, including a first transmission antenna connected to a first feeding line and a second transmission antenna connected to a second feeding line.

• The transmission circuitry in the radar apparatus performs multiplexing transmission of a transmission signal with a phase rotation amount corresponding to a Doppler shift amount from the transmission antennas.
• A phase deviation caused by a line length difference between the first and second feeding lines is an odd multiple of π/2.

Potential Applications: - This radar apparatus can be used in various industries such as aviation, meteorology, and defense for accurate detection and tracking of moving objects. - It can also be utilized in automotive applications for collision avoidance systems and adaptive cruise control.

Problems Solved: - The radar apparatus addresses the issue of accurately detecting and tracking moving objects by compensating for phase deviations caused by line length differences.

Benefits: - Improved accuracy in detecting and tracking moving objects. - Enhanced performance in various applications such as aviation, meteorology, defense, and automotive industries.

Commercial Applications: Title: Advanced Radar Technology for Enhanced Object Detection and Tracking This radar technology can be commercially used in aviation for air traffic control systems, in meteorology for weather monitoring, in defense for surveillance and target tracking, and in automotive for advanced driver assistance systems.

Questions about Radar Apparatus: 1. How does the radar apparatus compensate for phase deviations caused by line length differences?

  - The radar apparatus compensates for phase deviations by ensuring that the phase deviation is an odd multiple of π/2.

2. What are the potential applications of this radar technology beyond the ones mentioned in the summary?

  - The radar technology can also be applied in marine navigation systems, industrial automation for object detection, and search and rescue operations.

Original Abstract Submitted

Provided is a radar apparatus that includes: a plurality of transmission antennas including a first transmission antenna, which is connected to a first feeding line, and a second transmission antenna, which is connected to a second feeding line different from the first feeding line; and transmission circuitry, which, in operation, performs multiplexing transmission of a transmission signal, to which a phase rotation amount corresponding to a Doppler shift amount is applied, from the plurality of transmission antennas. A phase deviation due to a line length difference between the first feeding line and the second feeding line is an odd multiple of π/2.
