This report identifies and discusses two distinct dynamic components in a mathematical model of the stochastic motion of a laser spot on a moving target as viewed from the position of the designator. One of these components is contributed by manual tracking and possesses approximately second-order dynamics. The other component is contributed jointly by laser device and atmospheric propagation effects (scintillation) and exhibits nearly first-order dynamics. Both frequency-domain and time-domain...

The parameters influencing the effectiveness of simple devices used to perform signal, illumination and marker functions during a combat mission have been identified. An expression has been developed for the 'utility' of a device for performing a signal, illumination or marker function in a given environment. A technique has been developed for deriving a family of devices to be used by a combat unit for performing such functions in support of a mission. A numerical index of effectiveness is...

Television guidance systems have traditionally relied upon a human operator to designate a target before weapon release. This study uses computer simulations, which include a simulated terrain model, to evolve on-board hardware techniques for automatically designating targets after weapon release. Projectiles that use 128-line television guidance that automatically designates moving objects in a land target area are successfully simulated. (Author)

The 'spaceborne laser ranging system' is a proposed short pulse laser on board an orbiting spacecraft. It measures the distances between the spacecraft and many laser retroreflectors (targets) deployed on the earth's surface. The precision of these range measurements was assumed to be about plus or minus 2 cm. These measurements were then used together with the orbital dynamics of the spacecraft to derive the intersite vector between the laser ground targets. The errors associated with this...

The BRL and HEL are jointly investigating the effects of system nonlinearities on the accuracy of turret control systems with human operators in the loop. The system response at very low rates (one milliradian per second and less) is degraded because of the increased relative importance of nonlinear elements such as coulomb friction, backlash, and dead space. Good low rate response is necessary for accurate tracking of long range targets with laser designators and guided missile directors. This...

The capability of the Air Force to support the land battle at night has historically been late in development and inadequate by most standards. This ineffectiveness has resulted from the attempt to use equipment intended for daylight missions by aircrews who were inadequately trained for the night operation. 'Can do' aviators improvised tactics and eventually developed relatively successful night attack and close air support techniques. The need for better night equipment and specialized night...

This report documents the scan-scan correlator algorithms developed for the ASR-9 Processor Augmentation Card (9-PAC) project. The 9-PAC is a processor card that serves as a processing enhancement to the existing ASR-9's post-processor system. It provides increased speed and memory capabilities to the processor, which allows for the introduction of more complex primary and secondary surveillance algorithms. These more complex algorithms improve the ASR-9's system performance by offering...

New parametric space-time adaptive processing (STAP) based detectors are introduced and examined. Unlike conventional techniques that estimate the characteristics of the disturbance from only the secondary data, the proposed detectors obtain such knowledge jointly from the primary and secondary data. When the number of pulses within a coherent processing interval is sufficiently large, the proposed detectors can function even without any secondary data, making them strong candidates for...

This thesis presents a computer program designed to analyze the data from a TV camera for investigating laser beam propagation through the atmosphere. It uses aspects of Fourier optical theory to analyze the TV image to measure the effects of atmospheric disturbance and platform stability on the target spot. The understanding and analysis of these effects are increasingly important as lasers and other optical devices experience increased use in military application. (Author)

The effectiveness of a laser designator is dependent on the intensity and size of the beam placed on a target. This report describes a laser beam spread and wander test conducted at Holloman Air Force Base on August 18, 1994, by the Army Research Laboratory. To assess the performance of a helicopter-mounted laser, the beam was characterized by viewing and analyzing the diffuse reflections from a target board. The results are compared to a similar test conducted on June 7, 1994. Measurements...

An advance in the development of smart munitions entails autonomously modifying target selection during flight to maximize the value of the target being destroyed. Target identification and classification provides a basis for target value, which is used in conjunction with multi-target tracks to determine an optimal aim point for the munition. A unique guidance law can be constructed that exploits attribute and kinematic data from an onboard video sensor. This thesis develops an innovative path...

This work contributes to the Micropulse Laser Designation (MPLD) project. The objective of MPLD is to develop a 6-lb eye-safe micro-pulse laser system to locate, identify, range, mark, and designate stationary and moving targets. MPLD uses laser pulses of much lower energy and higher repetition rates than in existing laser designation systems. Because of this, MPLD presents a range of new circuit design and signal processing problems, and the present work seeks to address some of these...

The global war on terrorism has produced an elusive, nonlinear, and irregular threat on the battlefield. Countering this growing trend, the Marine Corps' maneuver warfare philosophy has evolved to include the concept of distributed operations (DO), which further takes advantage of the superior firepower, mobility, and command and control within the infantry battalion. The DO initiative, however, has largely stalled as a result of the intensive training it requires at the small unit level to...
