Bistatic RF Localization for Long-Range Tracking Under Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monostatic radar systems have limitations such as reduced detection range and susceptibility to interference from cluttering and jamming, which affect their effectiveness in tracking and intercepting objects like missiles and airborne threats.
Innovation Solution
A bistatic radio wave localization system uses two separate antennas for transmitting and receiving radio frequency (RF) waves, allowing for detection and tracking of objects beyond the range of monostatic systems, with a ground-based high-power transmitter and a lower-cost receiver on a flying object, and is less susceptible to interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monostatic radar systems are used, then the system structure is simple, but the detection range is reduced and susceptibility to interference increases
Solution Approach 1:
The radar system is segmented into separate transmitting and receiving functions located at different positions. The transmitter remains at the original location while the receiver is positioned remotely, allowing the system to maintain functional simplicity while improving detection capabilities and reducing interference susceptibility through spatial separation.
2Ease of operation
If monostatic radar systems are used, then the system is easier to operate, but tracking accuracy and reliability deteriorate
Solution Approach 1:
A communication link serves as an intermediary between the transmitter and receiver, enabling coordinated operation while maintaining ease of use. The receiver processes signals from multiple positions and combines this information with transmitter data to achieve improved tracking accuracy without complicating the operational interface.
3Reliability
If bistatic system with separate antennas is used, then detection range and reliability are improved, but device complexity increases
Solution Approach 1:
The system merges the transmitter and receiver functions into a coordinated bistatic configuration where the transmitter generates signals and the receiver processes them at a remote location. This combination approach maintains functional simplicity while achieving improved detection range and reliability through spatial separation of the antenna elements.

Implementation Method 1
A ground-based high-power transmitter transmits a radio frequency (RF) beam toward a target object and a lower-cost receiver on the flying object detects a scattered reflection of the RF beam from the target object
