“…Accounts of the history of bistatic radar make mention of the German Klein Heidelberg (KH) system, which used the British Chain Home radars on the south coast of England as the illumination sources [4,11]. It had seemed that this was largely a curiosity.…”

Bistatic radar has a history which dates back to the very earliest days of radar itself. It has been remarked that interest in bistatic radar has been cyclic, with a period of about fifteen years. Numerous experimental systems have been built and evaluated, though rather fewer operation systems. The purpose of this paper is to present and discuss recent developments that indicate that bistatic systems are now becoming practical for real, fielded applications, including passive bistatic radar (PBR) and bistatic SAR.

“…1 Rx beam set Rx site| The beam selection pattern is updated at a 5MHz rate according to a set of pre-loaded instructions stored in RAM memory within the BSU. The software control of the beam selection pattern allows the system to be re-configured for changes in site position or modulation simply by re-loading the BSU with new data.…”

“…Target location becomes a combination of time-measurement and triangulation, implying that all site positions, orientations and antenna pointing directions must be known a-priori at the receiver site. The geometry of the bistatic system means that the coverage area is severely distorted (1,2), with the position finding accuracy (as well as many other radar parameters) being dependent upon where a target lies in relation to the two sites, and the accuracy falling to zero for targets located along the baseline.…”

Long-baseline bistatic radar systems have been investigated and built in the past, but shortrange tactical applications of bistatic radar have not been explored in such detail. This paper briefly introduces the concept of bistatic and multistatic radar, compares the features of longbaseline and short-baseline systems, and describes a demonstration system designed to facilitate investigations into short-range tactical bistatic radar operation at X-band. This system, which is designed to be fully portable, features a phased array receiver with high-bandwidth digital beamforming, which can be used with a wide choice of modulations (pulsed and continuous), including high-PRF operation. 2.INTRODUCTION.

“…Many countries have invested heavily in the development of advanced surveillance systems and technologies. Of increasing concern is the threat that potential adversaries may use bistatic technologies to take advantage of significant investment in advanced sensors by our own countries [1,2]. With relatively inexpensive receiver systems, an adversary could use the signals as bistatic 'illuminators of opportunity'.…”

A set of theoretical techniques to prevent a radar from being used by a bistatic radar receiver as a non-cooperative illuminator are analysed. This works by radiating in addition to the radar signal waveform, a 'masking signal' waveform which is orthogonal to the radar signal waveform, both in the coding domain and the spatial domain. A number of different coding schemes are analysed. Two spatial coding methods are presented and analysed: the first uses a pair of interferometer elements at the extremities of the radar antenna array; the second uses a Butler matrix to generate a set of orthogonal beams. System-level calculations are presented to show the level of masking of the radar signal received by a bistatic radar receiver, and the suppression of the masking signal in the host radar echo. Some ideas for further work are presented.
