“…In practice the experimental Senrad system with Stretch pulse compression had a range resolution of 1 m and its antenna height was 55 m above the surface. If it is assumed that the multipath height-finding method is applicable when the pulsewidth ¿ < t h , then from (2) it is found that the experimental Senrad could utilize the multipath height finding method so long as the target's elevation angle was greater than about 1 deg. The above applies for a flat Earth, and has to be modified for a spherical Earth.…”

“…Ever since the inception of radar in the 1930s, the surveillance of air targets has been one of its most important applications. There have been many different types of radars developed for this purpose in many different radar-frequency bands [1][2][3][4][5][6][7]. Improved radars have appeared over the years as a result of the appearance of new technology or new requirements.…”

The generic characteristics and performance of an experimental long-range air-surveillance radar, known at the Naval Research Laboratory as Senrad, is described. Its distinguishing feature is that it can operate with simultaneous transmissions over a very wide bandwidth-from 850 to 1400 MHz. The technology and type of experimental radar equipment employed are discussed and examples are given of its performance capabilities obtained by means of very wideband operation. The unusually wide bandwidth of this radar allows 1) improved detection and tracking performance because of the absence of the nulls that are common in the antenna elevation radiation-pattern of a single-frequency radar; 2) moving target indication (MTI) without loss of targets due to blind speeds and without the need for multiple PRFs (pulse repetition frequencies); 3) accurate height finding with a fan-beam radar by taking advantage of the multipath time difference as a function of target height; 4) a form of limited target recognition based on high range-resolution; and 5) a reduction of the effectiveness of electronic countermeasures that can seriously degrade more narrowband radars.

“…Figures 1 and 2 are the radar coverage diagrams for the ARSR-2 and ASR-7, respectively (see Ref. 6). The 1-m 2 antenna patterns and pointing direction for the ARSR-2 and the ASR-7 are used to compute slant detection range at different altitudes.…”

“…Combat missions usually have one or more of the following as a primary goal: close air support; attacks against fixed, relocatable, and moving targets; air-to-air combat; suppression of enemy air defenses (SEAD); and battlefield interdiction. 6 Each of these combat missions involves a large amount of risk, and survival within enemy airspace is a critical factor.…”

The introduction of low observable (LO) technology on combat aircraft has produced a leap in aircraft survivability, but it has also raised some difficult questions. How do you quantify survivability, and because new technology tends to be expensive, how LO does an aircraft need to be to accomplish its mission? This paper will show how low observability dramatically improves combat aircraft survivability by reducing an air defense's ability to detect, track, intercept, and destroy an LO aircraft. Important aircraft signatures that can be detected such as radar, visual, infrared, and intentional emissions are discussed in detail as well as methods to reduce those signatures. LO and mission planning tactics' impacts on threat system capabilities are examined and examples of LO aircraft penetration of a notional hostile air defense are shown. The conclusion is that through the use of mission planning tactics and low signature, LO aircraft can survivably penetrate heavily defended air space with little support to accomplish their mission. Nomenclature C 3 = command, control, and communication P d = probability of detection P k = probability of kill P s = probability of survival
