Resource Overview

Monopulse Sum and Difference Beam Angle Measurement Program. This implementation uses an 8-element linear array to form simultaneous sum and difference beams for angle estimation. The algorithm demonstrates increasing error with larger measurement angles due to approximation methods and beam broadening during scanning. The code utilizes full-array beamforming techniques with phase-shift calculations for beam steering.

Detailed Documentation

This text describes a monopulse sum and difference beam angle measurement program. The implementation performs angle measurement using an 8-element linear array configuration, where the entire array simultaneously forms two beams - a sum beam and a difference beam. The algorithm employs complex weighting coefficients for each array element to create the beam patterns. As the measurement angle increases, we observe a gradual growth in estimation error. This error accumulation stems from the approximation method employed in the calculation and beam broadening effects that occur during beam scanning operations. The beamwidth expansion reduces angular resolution at larger offset angles, which is a fundamental characteristic of this monopulse technique. The code typically includes functions for array manifold calculation, beamforming weights generation, and angle estimation using the ratio of difference-to-sum beam outputs.
