“…In this paper, 't' and 'r' denote the transmitter and receiver, respectively. After reviewing the studies in the available literature [9,10,16,[38][39][40][41][42][43], we integrate the important results and then show that the flight path of spaceborne SAR can be equivalent to a curved path, which is mainly caused by the curved orbit and the rotating planetary surface and the flight path of the missile can be described by using the motion parameters, including the velocity, acceleration, and higher-order parameters, obtained from the information provided by the inertial navigation system (INS). According to the imaging geometry, the instantaneous slant range |r(η, A)| of the point A is expressed as:…”

The spaceborne transmitter/missile-borne receiver (ST/MR) synthetic aperture radar (SAR) could provide several unique advantages, such as wide coverage, unrestricted geography, a small detection probability of the missile, and forward-looking imaging. However, it is also accompanied by problems in imaging, including geometric model establishment and focusing algorithm design. In this paper, an ST/MR SAR model is first presented and then the flight-path constraint, characterized by geometric configurations, is derived. Considering the impacts brought about by the maneuvers of the missile, a non-'Stop-Go' mathematical model is devised and it can avoid the large errors introduced by the acceleration, which is neglected in the traditional model. Finally, a two-dimensional (2-D) scaling algorithm is developed to focus the ST/MR data. Without introducing any extra operations, it can greatly remove the spatial variations of the range, azimuth, and cross-coupling phases simultaneously and entirely in the 2-D hybrid domain. Simulation results verify the effectiveness of the proposed model and focusing approach. missile-borne SAR will inevitably bring some limitations, such as the large power antenna and high probability of being detected. Moreover, the monostatic SAR is incapable of forward-looking imaging, which seriously limits its applicability in the military field because information in the movement direction cannot be obtained directly. Compared with the monostatic missile-borne SAR, the ST/MR SAR has many advantages and they are:(1) The large-maneuver and receiving-only features of the missile-borne receiver reduce the detection probability. The corresponding anti-interference and anti-interception are greatly improved in the ST/MR SAR system. (2) The radar antenna, installed on the missile-borne platform, is used to receive the echo signals without a transmitting function, which indicates that a large power device can be avoided in the missile system to greatly save space and costs.(3) Spaceborne transmitter has the characteristics of wide coverage, unrestricted geography, net flexibility, and a high revisiting-frequency, which could provide some degrees of freedom (DOFs) in target area selection, flight trajectories, and number of missile-borne receivers. (4) By setting the transmitter and receiver on different platforms with a special style, the non-complete coupling areas between iso-range and iso-Doppler lines could be formed in front of missile, which means that the missile has the capability of forwarding-looking imaging.Note that these advantages for the ST/MR SAR also hold for other BiSAR systems, such as the spaceborne/airborne SAR and the airborne BiSAR, which are of special significance for the missiles mainly applied in the military fields. Generally, these common features of the BiSAR can avoid disadvantages inherent in the monostatic missile-borne SAR and make the ST/MR SAR a flexible and effective tool for information retrieval [11][12][13][14][15]. However, there are also a number of problems broug...

“…Current systems employ mission-specific hardware and waveforms. There are some existing multi-mode radar systems that have the ability to perform different missions [4], although not simultaneously [1]. By reducing the amount of required hardware and containing a large amount of information from a single waveform, a simultaneous multi-mission radar platform would be the most efficient to date.…”
