The projected use of active array multifunction radars is increasing significantly, paced by the rapid rise of GaAs integrated circuit technology, and the ability of this type of radar to economically perform a wide variety of functions which previously required separate systems. In the tactical arena, these functions range from surveillance and tracking to missile guidance, threat illumination, and kill assessment. The demands on waveform planning and energy management are heavy, however, and become even more so when the radar is used as a shared aperture, adding such functions as communications and navigation. The work described here represents research into waveform selection and energy management algorithms using an AI based weapons system simulation as a system testbed and analytical tool.<>

Summary form only given, as follows. The kinematic GPS landing system (KGLS) uses differential GPS carrier phase data to navigate landing aircraft. As the aircraft overflies a "GPS marker beacon" during its approach, the KGLS sensor uses beacon data to resolve the carrier phase integer ambiguity. This deterministic method provides centimeter-level accuracy and high reliability on every approach.<>

One objective of the dual-use technology concept is to extract more value from Department of Defense research and development spending.

Active electronically scanned arrays (AESAs) offer significant operational and reliability advantages compared to other types of radar-systems. However, their use for either military or commercial applications has been limited. The primary reason for this is the high cost of the array components. This paper discusses the present status of technology for scanned arrays and provides a suggested approach for developing the technologies and infrastructure necessary to produce the arrays of the future at an affordable cost.<>

The development of highly efficient, optically activated, semiconductor switches will yield compact radar transmitters that can be applied to airborne surveillance missions on unmanned air vehicles. Radar systems employing these high peak power sources must use ultrawide band antenna elements to efficiently meet system performance requirements. Unfortunately nearly all antenna elements that can meet the bandwidth requirements are undesirable for the airborne application because of their geometry and orientation necessary to utilize the maximum directivity. The equiangular spiral is a planar element which is suitable for the airborne application. This paper presents a heuristically derived expression for the transient radiation from this antenna and examines the performance of an ultrawide band active array composed of equiangular spiral elements, including beam forming and compensation of the waveform dispersion introduced by the spiral.<>

As a step to the development of regional positioning systems using geostationary satellites, the authors tried deducing positions of a ship steaming in Tokyo Bay, by making use of three transmitters of TV signals; two geostationary satellites, BS (110/spl deg/E) and Super Bird (162/spl deg/E), and Tokyo Tower (139.75/spl deg/E, 35.67/spl deg/N). The high stability of the synchronous pulses in the video signal makes it possible to find a range more accurately. The RMS error of 240 positions calculated every second on the ship navigating up Uraga Channel is 9.7 m longitudinally and 6.4 m latitudinally in reference to the positions by GPS. But we suspect that the GPS positions might have been modified by the Kalman filter, for the longitudinal error observed at a fixed point (Tokyo University of Mercantile Marine) is as small as 2.9 m.<>

The Amber Radiance 1 infrared imaging camera system is a high performance, portable, precision instrument based on a staring indium antimonide focal plane. It has been developed using technologies that were initially motivated by department of defense requirements. Government funding and company development funds have transitioned this technology into a standard commercial product resulting in outstanding performance, low cost, and particularly well suited for insertion into unmanned vehicle applications. Dual use IR technology has been demonstrated, but administrative hurdles exist that prevent full commercial exploitation of the technology. The performance of the camera is excellent demonstrating as low as 23 mK NEdT at 300 K.<>

An efficient 3-channel radar system is derived that provides both clutter cancellation and high resolution angle estimates simultaneously for a space-based radar (SBR). A phased array antenna divided into three DPCA (displaced phase center antenna) sub-apertures is assumed. The paper provides expressions to perform clutter cancellation and calculate monopulse angle estimates, along with simulation results to illustrate their performance.<>

A novel technique is proposed for collision avoidance radar used in automobiles, in which new six-port microwave/millimeter wave digital phase/frequency discriminator (SPFD) is used to measure Doppler frequency shifts. Both relative speed and moving direction of the target are readily obtained. Ranging is implemented by the measurement of phase difference at two adjacent frequencies. Preliminary experimental simulation proves the validity of the proposed alternative approach.<>
