AIRBORNE COMPLEX FOR REMOTE SENSING ACRS-28 |
  |
The airborne complex ACRS-28 is installed onboard the aircraft AN-28 and comprised of the following sensing facilities:
- a Ka-band SLAR with a 15-km swath (3000 m - flight altitude), a 10-m spatial resolution, a contrast-background sensitivity of 0,5 dB and a vertical polarisation;
- an IR scanning radiometer "Malakhit-1" with a swath with of 3,4 H (of the flight altitude), a resolution of 1,7 milliradian and sensitivity of 0,1° K;
- a multichannel trace videospectrometer "Kvarts-3102" with an operating range of 400 to 800 nm, the number of channel - 1000, the 0.03 sec - period of a single spectral measurement;
- a videocamera.
Towards the end of 1998 this complex is expected to be additionally equipped with a L - band SAR having a 10-m spatial resolution, a 15-km swath and a complete set of polarisations of transmitted and received signals.
The ACRS-28 is intended to solve a wide range of remote sensing problems including:
- operational monitoring of floods and underfloodings;
- prompt detection of oil and other surfactant spilled out on the water surface;
- efficient evaluation of ice conditions on the sea and inland water basins;
- the search of broken-away ice floes and the rescue of personnel;
- operational monitoring of large-scale fires;
- prospecting of mineral resources and the search for different constructions;
- evaluation of soil status (carrying-out of cadastral operations) and the vegetation cover;
- detection the ships violating the maritime trade and industrial zones (to name but a few).
The ACRS-28 comparses favorably with other airborne remote sensing systems in the optimal combination of cheap but efficient radar, optical and IR facilities.
