An Analysis of Cost Versus Performance Relationships for Phased Array Radars

L. A. Rondinelli

ResearchPublished 1967

Cost estimating relationships between the performance requirements of phased array radars and their hardware and installation cost are developed for both the search and tracking functions. Appropriate performance parameters for each function are derived from system operational requirements, and Lagrange multipliers are used to obtain the optimum design formulas and minimum-cost equations. Results of several phased array cost examples are analyzed to test the sensitivity of the cost estimates to variations in required system performance and in the cost coefficients of the cost equations. The use of higher power modules at lower cost per watt results in less expensive search arrays. For tracking array designs, the situation is reversed. By a compromise design, the same array can be used for both functions.
