Receiver Operating Characteristic Plot

Receiver Operating Characteristic Plot

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...

Errors in Global Positioning System

Errors in Global Positioning System

Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Background:

High-power deception jamming poses a significant threat to radar systems.
Orthogonal frequency division multiplexing (OFDM) radar offers potential for advanced signal processing.
Existing electronic counter-countermeasures (ECCM) techniques may be insufficient against sophisticated jamming.

Purpose of the Study:

To propose an effective ECCM technique for OFDM radar against high-power deception jamming.
To develop methods for suppressing velocity, range, and joint range-velocity deception jamming.
To optimize phase codes of OFDM subcarriers while managing the peak-to-average power ratio (PAPR).

Main Methods:

Designing pulse initial phases to create Doppler spectrum notches for velocity deception jamming.
Optimizing subcarrier phase codes to minimize jamming power in range and range-velocity domains.
Formulating and solving a non-convex optimization problem for phase code optimization using the Phase-Only Alternating Direction Method of Multipliers (POADMM).

Main Results:

The proposed ECCM technique effectively suppresses various types of deception jamming.
Phase encoding ensures constant energy per OFDM symbol, as per Parseval's theorem.
The POADMM method successfully optimizes phase codes under global PAPR constraints.

Conclusions:

The developed radar signaling strategy provides effective suppression of high-power deception jamming.
The POADMM algorithm offers a viable solution for optimizing phase codes in OFDM radar ECCM.
The proposed technique enhances the resilience of OFDM radar systems against sophisticated jamming attacks.
