Abstract

The Advanced Sensors Directorate of the Army Missile Command's Research, Development, and Engineering Center (RD&EC) provides specialized technical support to the HELLFIRE and COPPERHEAD Project Offices for the HELLFIRE missile, the COPPERHEAD projectile, and ground laser designators. The HELLFIRE and COPPERHEAD laser seekers are supported by RD&EC's Automated Laser Seeker Performance Evaluation System (ALSPES). This facility was conceived by RD&EC engi-neers and put into operation in 1978. Laser energy incident from different angles test the seeker's ability to track target reflections; while multiple lasers aimed at the seeker test the false target rejection capability of the seeker. The following tests can be performed on the seeker from a computerized test console: spin-up time, scan pattern, threshold sensitivity, AGC calibration, transfer function, static track rate error, guidance noise, gimbal angle linearity, dynamic boresight shift, correlation/decorrelation logic, last pulse logic (false target discrimination), field-of-view, frequency response, guidance noise vs energy, and gyro drift. The 15 characterization tests can be accomplished in approximately 4 hours using this computerized facility. The ALSPES has identified several design abnormalities in laser seekers, resulting in corrective actions that have increased system performance and reliability.
