Are you sure? That's an almost impossibly high receive bandwidth for an older type of equipment I would think. I've seen bandwidth ranges of 50Hz to 300Hz (that's Hz not KHz or MHz). This is swept or chirped over a frequency (bigger is better for that - so 200Mhz good and they'd probably want more). But in terms of a guard, you should be able to guard much tighter than 200Mhz - that's what I'm not understanding - but haven't looked at it closely.

Frequency Modulated Continuous Wave radars used for most civilian radar altimeters sweep most of 200 MHz bandwidth, largest known case is 196 MHz. Transmit power ranges between 0.1 to 100W.[1] As another commenter mentioned, making a broadband filter for such wide bandwidth is... problematic, and it's one of those devices where you might want to use fixed function rather than SDR.
