Summary
Optimizing non-cooperative passive multistatic radar (PMR) systems enhances maritime domain awareness. This study optimizes receiver placement, reducing positioning error by 8.9% and extending detection range by 15.8% for improved maritime monitoring.
Area of Science:
- Electrical Engineering
- Oceanography
- Signal Processing
Background:
- Traditional active radars face limitations in complex electromagnetic environments, including high costs and interference susceptibility.
- Non-cooperative passive multistatic radar (PMR) systems offer advantages like low cost, environmental sustainability, and resilience, making them attractive for maritime monitoring.
- Comprehensive maritime domain awareness is vital for navigation safety, traffic management, and security surveillance.
Purpose of the Study:
- To analyze the detection performance of multistatic radar systems.
- To propose an optimization method for transceiver configuration in non-cooperative PMR systems.
- To determine optimal receiver placement for enhanced maritime surveillance.
Main Methods:
- Developed a multi-objective optimization model considering detection coverage and positioning error.
- Utilized geometric coverage theory and a signal-to-noise ratio model for analysis.
- Employed the Non-dominated Sorting Genetic Algorithm II (NSGA-II) to solve the optimization problem.
Main Results:
- Optimized receiver placement reduced positioning error by approximately 8.9%.
- Detection range was extended by approximately 15.8% compared to random placement.
- Optimal receiver placement was found within 15 km of the transmitters' geometric center for the studied S-band configuration.
Conclusions:

A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

In coordinate geometry, determining the central point between two locations is common. This central point, or midpoint, lies exactly halfway along the line segment connecting two points in a two-dimensional space. It has applications in mathematics, physics, engineering, and various planning disciplines.Given two points labeled as A (x1, y1) and B (x2, y2) on a coordinate plane, a straight line segment can be plotted between them. The midpoint, labeled point M, divides this segment into two...
