  • The condition number of sensitivity matrix is a key factor that influences the performance of InSAR calibration. On the basis of InSAR calibration theory, basic principles of locating calibrators are proposed, and constraints of locating calibrators are also derived. Under the theory of condition number minimization, an algorithm of locating calibrators is presented to minimize the sensitivity matrix condition number. Theoretic analyses and computing results show that the algorithm is efficient.
