You wouldn't happen to have a link would you? describing the sensor, be it a news article or even a Wikipedia page. not for the Su-24 targeting system specifically, but even the one used for airfields.
Doppler LiDAR information can be found here:
Mu data gave me an overall lenght of 2500mm for a body diameter of about 50 cm i.e. about 1 to 5, when a mk80 series (and subsequentely Jdams) reach 1/8.
You are comparing the length to weight ratio of a cluster bomb with a iron bomb?
OK then... the US equivalent cluster bomb would be the CBU-97... it has a length of 2.34m and a diameter of 40cm... which is nothing like a 1/8 ratio.... actually a 5.8 ratio or there abouts.
Wow... Russian cluster bomb is super fat, while ultra skinny US bomb is marginally narrower...
Let's note that the fact RuAF still prefer to uses high drag bomb like the M1954 and above all the OFAB 250/270 even with the SVP-24 give probably an hint how the precision of system vary with the type of weapon used.
shorter fatter bombs make more sense with internal bomb bays like on Tu-22m3s.
Equally the aircraft carrying these bombs are not flying low level at supersonic speed so drag is not actually an issue.
The SVP-24 takes into account the ballistic performance of the weapon selected so the drag level of the bomb is not relevant.
Having a high drag bomb shape means it does not need a drag chute to allow safe low level release.
As long as drag is calculated into the free fall algorythm a high drag bomb should actually fall faster and slow horizontal speed faster which would actually make it more accurate, not less accurate.
