A Targeting Problem Exact versus Expected-Value Approaches.

APR 1980

Authors: Maurice Mizrahi; CENTER FOR NAVAL ANALYSES ALEXANDRIA VA NAVAL WARFARE ANALYSIS GROUP

This paper solves a targeting problem exactly and compares the exact solution with several reasonable expected-value approaches in order to gauge their accuracy. The scenario consists of air-to-surface missiles fired simultaneously at a ship formation defended with point defenses. The problem is to find the probability that a given ship will survive the raid. Each ship is present with a given probability and possesses a targeting 'weight' determining the likelihood ...

Air-to-air missile endgame programs typically require tens of seconds of computer time to calculate a single estimate of probability of kill (P(K). Thousands of these estimates may be required in any given endgame analysis. The main objective of this research was to develop a method for characterizing an endgame model using only a fraction of the amount of data generated by such analyses. In pursuit of this objective, a second ...

Modular Digital Missile Guidance.

30 JAN 1980

Authors: Frank J. Langley; John Demetrick; Frank Marchilena; RAYTHEON CO BEDFORD MA MISSILE SYSTEMS DIV

Higher throughput general-purpose processors have traditionally been the domain of Schottky-bipolar or CMOS-SOS integrated circuit technology with attendant multi-component packaging logistics and support software problems. In addition, the modular operational software has proven difficult to achieve in practice. To combat these deficiencies, a super-federated high-speed, multi-processor architecture has been explored using standard industry 16-bit microprocessors. The resulting design evolved in this study employs a time-phased ring approach to high throughput ...

Nonlinear Guidance of Air-to-Air Missiles

11 JUN 79

Authors: Jan F. Andrus; NEW ORLEANS UNIV LA DEPT OF MATHEMATICS

In earlier work the necessary conditions of optimality were derived for a problem of minimum miss-distance guidance of air-to-air missiles. The model was based upon nonlinear translational equations of motion. The solution of the necessary conditions requires a solution of a two-point boundary- condition problem. Two methods proposed for the latter solution, an elliptic integral method and a series technique, were studied and both methods were rejected in favor of ...

Dual Control Analysis of an Air to Ground Missile.

MAR 1978

Authors: James P. Kauppila; AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OHIO SCHOOL OF ENGINEERING

Many errors are known to exist in Inertial Navigation Systems of modern air-to-ground missiles. These error sources, if undetected, contribute to navigation errors of position and velocity. This study analyses one source of INS errors -- the misalignment of the accelerometer reference frame. By maneuvering a missile, the error source becomes more observable. Thus, a better estimate can be made of the error source. This directly influences the estimate of ...

Authors: Joseph M. Schallert; DEPARTMENT OF THE NAVY WASHINGTON DC

The combination of a stepped piston with gas port unclosing is provided to vary the effective piston area and meter gas simultaneously during the separation of missiles from launching aircraft. Sequentially exposing the metering ports permits flow restriction and, therefore, effective force control initially, plus a programmed buildup as piston velocity increases and pressure decays. The time to reach peak ejector force is increased, the peak force is decreased, and ...
