In summary, the paper discusses the maximum theoretical angular accuracy of planar and linear arrays of sensors. Equations 19 and 20 provide accuracies for the x and y axes. The angle between the incoming ray and the normal direction to the array does play a role, with the best accuracy achieved when the ray is along the normal direction. As the angle of incidence moves off of broadside, the angular resolution and SNR decrease due to the shrinking of the array's normal direction. Additionally, the accuracy and resolution vary with different directions of incidence.

I'll need to look at that paper...

The maximum theoretical angular accuracy of planar arrays refers to the maximum possible precision in determining the direction of incoming signals using a planar array antenna. It is determined by the spacing and number of elements in the array, as well as the frequency of the signals being received.

The maximum theoretical angular accuracy of planar arrays can be calculated using the formula: θ_max = λ / (2 * N * d), where θ_max is the maximum theoretical angular accuracy, λ is the wavelength of the signal, N is the number of elements in the array, and d is the spacing between elements.

Yes, the maximum theoretical angular accuracy of planar arrays can be improved by increasing the number of elements in the array, decreasing the spacing between elements, and using higher frequency signals. However, practical limitations such as size and cost may prevent achieving the maximum theoretical accuracy.

The maximum theoretical angular accuracy of planar arrays can be affected by various factors such as environmental conditions (e.g. weather, interference), imperfections in the array's construction, and limitations in signal processing algorithms.

The maximum theoretical angular accuracy of planar arrays is used as a benchmark for evaluating the performance of planar array antennas in real-world applications. It serves as a guide for engineers and scientists in designing and optimizing array antennas for specific purposes, such as radar systems, communication systems, and wireless networks.
