Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MIMO and multistatic radar systems face challenges in efficiently sharing limited space and channel access, leading to latency, unfair utilization of apertures, and detectable traffic spikes before radar missions due to suboptimal scheduling and role designation algorithms.
Innovation Solution
A radar activation multiple access system with a multiple access unit that includes a scheduler, synchronization, priority assignment, and radar activation components to manage time divisions, synchronize nodes, and determine roles based on priority, preventing simultaneous transmissions and ensuring fair bandwidth utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sequential handshaking scheduling is used to determine transmitter and receiver roles, then role assignment is achieved, but latency and signal loss increase
Solution Approach 1:
The system pre-assigns roles and schedules transmissions before the actual radar mission begins. The multiple access unit determines which nodes will be transmitters or receivers in advance, eliminating the need for real-time sequential handshaking during the mission, thus reducing latency and signal loss.
2Ease of operation
If traditional scheduling algorithms are used to select and designate aperture roles, then role designation is achieved, but aperture utilization becomes biased and unfair
Solution Approach 1:
The multiple access unit continuously monitors the performance and status of each radar node, using this feedback information to dynamically adjust role assignments and scheduling decisions. This ensures that all apertures are utilized fairly and efficiently based on their actual performance characteristics rather than fixed algorithmic biases.
3Reliability
If transmitters and receivers are activated before a radar mission is requested, then system readiness is improved, but detectable traffic spikes occur
Solution Approach 1:
The system employs periodic low-level communication and role assignment updates that maintain system readiness without creating detectable traffic patterns. The multiple access unit schedules occasional status checks and role reaffirmations that keep the radar network prepared while avoiding the large traffic spikes associated with pre-mission activation sequences.

AI summary
A radar activation multiple access system and method is provided that includes a plurality of radar participant nodes wirelessly connected and forming a radar network and a multiple access unit in communication with the radar network. The multiple access unit includes a scheduler component, a synch component, a priority component and a radar activation component. The scheduler component is configured to schedule a period of operation having a plurality of time divisions within the period of operation. The synch component is configured to synchronize the radar participant nodes within the period of operation. The priority component is configured to assign a priority to individual radar participant nodes in the radar network. The radar activation component is communicatively connected to the radar network and configured to determine a contentious state at a time division in the period of operation. The radar activation component instructs individual nodes to assume the role of transmitter or receiver based on the assigned priority.
