1. A system for determining the line-of-sight angular rate to a target comprising:

  • first means for determining range rates {dot over (R)}i of the target relative to at least two projectiles, wherein said first means includes a monostatic millimeter wave radar which measures the range, range rate and angle of the target, and the range, range rate, angle, and angle rate of each projectile;

    second means for determining the position and velocity of each projectile;

    third means for calculating the line-of-sight angular rate of the target relative to at least one projectile {circumflex over (ω

    )}i from said range rates, positions, and velocities; and

    fourth means for obtaining a bistatic range rate {dot over (R)}B from each of the projectiles, wherein said fourth means is included in said first means.
