Solution Overview

Problem

Existing wireless communication systems face challenges in optimizing antenna patterns for both transmission and reception to enhance detection volume and signal efficiency, particularly in environments where wired connections are impractical.

Innovation Solution

The method involves determining and adjusting the parameters of both transmitter and receiver antenna patterns to form a conjoint beam shape, optimizing the antenna system radiation pattern by convolving the individual radiation patterns of the transmitter and receiver arrays, and iteratively adjusting these parameters to match a desired radiation pattern, thereby enhancing detection capabilities.

Solution Approach 1:

The patent merges the optimization of transmit and receive antenna parameters into a unified conjoint optimization process. The system determines a combined radiation pattern that accounts for both transmission and reception characteristics simultaneously, rather than optimizing them separately. This integration allows the system to achieve improved detection volume and signal efficiency by considering the interactive effects between transmit and receive antenna patterns.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic adjustment of antenna parameters based on operational conditions. The system iteratively refines antenna parameters to match desired radiation patterns, allowing the antenna system to adapt its beam shaping characteristics in response to changing environmental conditions and detection requirements, thereby optimizing both individual performance and system-wide detection capabilities.

Inventive Principle:

If antenna parameters are adjusted to maximize detection volume, then detection capabilities are improved, but system complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent employs feedback mechanisms where the system evaluates the actual radiation pattern produced by the antenna system and compares it against desired patterns. Based on this comparison, the system iteratively adjusts antenna parameters to reduce discrepancies. This feedback-driven approach automates the complex optimization process, making it manageable while achieving enhanced detection volume through systematic parameter refinement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent implements preliminary determination of desired radiation patterns before actual operation. By pre-calculating target patterns and using them as reference points for optimization, the system simplifies the real-time adjustment process. This preliminary action provides a clear optimization target, reducing the complexity of parameter adjustment while maximizing detection volume.
