1 year ago Two things spring immediately to mind with the request. 1, The quoted pulsed parametrics are not those of a pulse doppler radar. Its a traditional pulsed radar.
- The range resolution is mathematically a lot better than the 180 metres quoted. Just on eclipsing it will have a min resolution of around 38 metres so wondering if this is a typo
