Abstract: In this project, the feasibility study of passive airborne radar is discussed. Monostatic airborne passive radar scenarios are simulated instead of bistatic or monostatic ones due to the complexity of such radars. A passive airborne radar works by sending a signal through its transmitter which reaches the target. The reflected echo then travels towards the airborne receiver. In the first few chapters, fundamental radar architecture will be explained. After which, the use of software to investigate techniques to simulate how a radar works will be discussed. The use of both sample matrix inversion(SMI) and weight computations are simulated and covered in this report. The various architectures of Space-Time Adaptive processing (STAP) such as Pre-Doppler and Post-Doppler techniques are also covered. The fully adaptive STAP is first explained. To reduce the dimension and complexity of computations of covariance matrices, partially STAP is then introduced. This includes Pre-Doppler and Post-Doppler techniques. Pre-Doppler techniques such as the Element-Space Pre-Doppler simulations are processed using MATLAB, followed by the simulation of Post-Doppler techniques including Post-Doppler Adaptive Beamforming and Multiwindow Post Doppler STAP. Some techniques are then compared and analysed through the simulation of the signal-to-interference-noise ratio (SINR) loss.
