Target Tracking While Jamming by Airborne Radar for Low Probability of Detection

Area of Science:

• Aerospace Engineering
• Electronic Warfare
• Signal Processing

Background:

• Minimizing radiation power is crucial for stealth aircraft's low probability of detection (LPD) against passive detection systems (PDS).
• Limitations exist when PDS performance advances, necessitating alternative tactics.
• Target tracking scenarios require maintaining LPD for airborne radar.

Purpose of the Study:

• To propose an interference tactic for airborne radar to maintain LPD in target tracking scenarios.
• To develop a mathematical model for minimizing airborne jammer interference power.
• To ensure interference does not disrupt target tracking.

Main Methods:

• Minimizing airborne radar radiation power based on radar-target distance.
• Minimizing airborne jammer radiation power based on predicted PDS detection probability.
• Analyzing Constant False Alarm Rate (CFAR) technologies (Cell Average, Greatest of, Smallest of, Ordered Statistic) in PDS.
• Establishing a mathematical model considering detection probabilities and time synchronization to minimize jammer interference power.

Main Results:

• The proposed interference tactic effectively keeps airborne radar in an LPD state.
• The mathematical model successfully minimizes airborne jammer interference power.
• Simulation results validate the effectiveness of the proposed model in avoiding interference with target tracking.

Conclusions:

• The developed interference tactic is effective for maintaining airborne radar's LPD against advanced PDS.
• The mathematical model provides a method to optimize jammer power while preserving target tracking.
• This approach enhances stealth capabilities in complex electronic warfare environments.
