“…The AF is well known in the monostatic [17] and bistatic [18,19] cases and is the most commonly used tool to assess radar waveforms. The monostatic AF is extended to the bistatic case for transmitted signal s(t) as [18,19] …”

Passive radar provides a means of spectrum sharing in a congested environment. In passive radar, the radar design problem is one of emitter selection, rather than waveform optimisation. This study combines relevant criteria (signal-to-noise ratio, ambiguity function integrated sidelobes, effective multistatic resolution area and contrast ratio) in a multiobjective optimisation to select subsets of available emitters for passive multistatic synthetic aperture radar (SAR). Extensions to wellknown monostatic and bistatic performance criteria are defined for the multistatic SAR case. Assumed limitations in the number of available receiver channels constrain the emitter selection. The proposed emitter selection framework is demonstrated for a simulated scenario of 24 analogue and digital emitters, with a constraint of four receiver channels. Results indicate that the proposed ranking successfully differentiates between emitter sets resulting in good images and those sets resulting in poor images, providing a first step towards formulating a general image quality equation for multistatic SAR.

“…Monostatic radar ambiguity function has been fairly well developed, and a variety of examples can be found in literature [23]. The ambiguities of bistatic radar and netted radar have also been investigated by [22] and [36]. Generally speaking, the signals from GSM have much less range and Doppler ambiguities than other signals of opportunity, which makes them more suitable for passive radar.…”

To protect the homeland from terrorist attacks employing explosive devices, revolutionary advances across a wide range of technologies are required. Inspired by recent advances in near-space (defined as the region between 20 km and 100 km), this paper proposes a new passive radar system using opportunistic transmitter as an illuminator and near-space platform as a receiver. This concept differs substantially from current radars. This system can be operated as a passive bistatic or multistatic radar and hence largely immune to jamming. By placing the receiver in near-space platforms, many functions that are currently performed with satellites or airplanes could be performed much more cheaply and with much greater operational utility. These advantages make near-space passive attractive for a variety of applications, many of which fit well with the needs of homeland security. This paper details the role of near-space passive radar as sensor system that can support homeland security applications. The strengths and weakness of near-space passive radar, compared to current spaceborne and airborne radars, are detailed. The signal models and processing algorithms for near-space passive radar are provided. It is shown that the use of cost effective near-space platforms can provide the solutions that were previously thought to be out of reach to remote sensing and government customers.

“…The dependence of the ambiguity function of a bistatic radar on geometry has been evaluated by Tsao et al [9,10]. They showed that, because delay time is no longer a linear function of target range and Doppler is no longer a linear function of target velocity, the form of the ambiguity function depends greatly on the position and direction of motion of the target.…”
