The tracking sensitivity of radar-based space debris tracking systems can be further improved if they are working in conjunction with another transmitter or receiver, forming a bistatic radar system.
22.
The receiver continues working, allowing occasional bistatic radar measurements, where the radar signal is transmitted from the Earth, reflected off the Moon, and received by the Mini-RF.
23.
The B-21, however, required to provide an answer to the fifth generation defense systems ( such as SA-21 Growlers, bistatic radar and active electronically scanned array radar ).
24.
Another attempt to revive the RDF 1.5 concept, today known more generally as bistatic radar, was made in March 1940 when a modified set was mounted in Bristol Blenheim " UK coastline.
25.
Another experiment performed on " Apollo 15 " involved using the radio signal of " Endeavour " and was termed the Downlink bistatic radar Experiment to find the dielectric constant of the surface material.
26.
Doppler radars are used in aviation, sounding satellites, meteorology, radar guns, radiology and healthcare ( fall detection and risk assessment, nursing or clinic purpose ), and bistatic radar ( surface-to-air missile ).
27.
Late in 1935, responding to Lindemann's recognition of the need for night detection and interception gear, and realizing existing transmitters were too heavy for aircraft, Bowen proposed fitting only receivers, what would later be called bistatic radar.
28.
Null and filter approaches must be used with bistatic radar, like semi-active radar homing, for practical reasons because side-lobes from the illumination radar will illuminate the environment in addition to the main-lobe illumination on the target.
29.
In a bistatic radar with wavelength " ? ", where the distance between transmitter and target is " R tx " and distance between receiver and target is " R rx ", the received bistatic Doppler frequency shift is calculated as:
30.
The RAX-1 mission, launched in November 2010, was a demonstration of the team s technological capabilities it made great strides in CubeSat design, and was able to execute bistatic radar measurements that had never before been performed on a satellite of its size.
