Abstract
Systems and method for detecting and removing an arbitrary phase difference between a sum channel signal and a difference channel signal in a monopulse system. A sum channel signal is received from a sum channel signal source and a difference channel signal is received from a difference channel signal source. The difference channel signal is shifted according to various potential arbitrary phase differences φand φ+π (where φis from 0 to π radians, i=0, 1, . . . , n; φ+π going from π to 2π radians) between the sum and difference channel signals to thereby generate difference channel signals each having a different phase. The difference channels having a different phase are combined with the sum channel signal to generate a plurality of sum+difference signals and sum−difference signals. Based on the plurality of sum+difference signals and sum−difference signals, maximum in-phase and out-of-phase correlations are determined from the φand φ+π pairs. The maximum in-phase and out-of-phase correlation pairs are used in an error estimate calculation.
