AESA TX PULSE PAIR RADIATION PATTERN PHASE CONJUGATION FOR LOW SIDE LOBE / MAXIMUM EIRP RADIATION PATTERN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240319330 titled 'AESA TX PULSE PAIR RADIATION PATTERN PHASE CONJUGATION FOR LOW SIDE LOBE / MAXIMUM EIRP RADIATION PATTERN
Simplified Explanation:
The radar system described in the patent application uses an AESA to illuminate a target with two pulses, creating a radiation pattern with nullified side lobes through superposition of return signals.
- The radar system includes an AESA that illuminates a target with two pulses.
- The first pulse sets the desired beam pointing angle (azimuth and elevation).
- The second pulse defines a radiation pattern with side lobes out of phase with the main beam.
- Return signals are received and combined to nullify the side lobes through superposition.
- The radar processing unit interprets the pulse-pair as a single ultra-low level side lobe return radiation pattern.
Potential Applications: This technology can be used in military radar systems, surveillance systems, and air traffic control systems.
Problems Solved: This technology addresses the issue of side lobes in radar systems, improving accuracy and reducing interference.
Benefits: The benefits of this technology include enhanced target detection, improved signal clarity, and reduced interference from side lobes.
Commercial Applications: Potential commercial applications include defense contractors, radar system manufacturers, and companies involved in surveillance technology.
Prior Art: Prior art related to this technology can be found in patents related to radar signal processing and AESA technology.
Frequently Updated Research: Research on radar signal processing techniques and AESA technology is frequently updated, providing new insights and advancements in the field.
Questions about radar signal processing technology: 1. How does the superposition of return signals help nullify side lobes in radar systems? 2. What are the key advantages of using an AESA in radar signal processing technology?
Original Abstract Submitted
a radar system including an aesa illuminates a target with a first pulse for a desired beam pointing angle (azimuth and elevation). the aesa then illuminates the target with a second pulse for the desired pointing angle, the second pulse defining a radiation pattern with a main beam in phase with the first pulse, but side lobes that are out of phase. the radar system receives return signals and combines the return signals to null the side lobes by the principle of superposition. the radar processing unit is time synced such that the pulse-pair is interpreted as a single ultra-low level side lobe return radiation pattern.
