abstract = {This work investigates a dual-antenna passive synthetic aperture Direction-of-Arrival (DoA) estimation technique for compact airborne sensors under simulated uncertainties in platform navigation and receiver synchronization. An electromagnetic environment incorporating spherical wave propagation and Doppler effects is implemented in an in-house radar simulator. We analyze how practical issues such as velocity variations, misleading sampling rates, and local-oscillator frequency offsets can degrade the accuracy of the proposed DoA estimator, highlighting trade-offs between aperture length, snapshot budget, and tolerance to measurement noise. Our results indicate that the proposed signal model for dual-antenna passive synthetic aperture is capable of dealing with even moderate misleading measurements and still arriving at useful azimuth and elevation estimates.},

abstract = {Direction-of-Arrival (DoA) estimation is critical for various applications such as radar, sonar, and wireless communication, where the identification of radio frequency (RF) source localization is essential. This paper presents a passive detection technique using a synthetic aperture with a single sensor element. The method leverages the sensor's movement to form a synthetic aperture, reducing system complexity and cost while maintaining high accuracy. Simulation results demonstrate the technique's effectiveness under different conditions, showing its potential for practical applications in surveillance, navigation, and RF interference detection and suppression.},
