Radar signal time and space real-time selection device and selection method

The invention provides a radar signal time and space real time selection device and A selection method; the radar signal time and space real time selection device comprises wide wave gate signal (1), a coincidence gate (6) of pulse stream signal (2), analog-to-digital transformations of A/D 7 and A/D 8 of Phix3 and Phiy4, a filter (9) and a time changeable wave gate (10); the wide wave gate (1) and the pulse stream signal (2) of wide wave gate are input into the coincidence gate (6) firstly and then are input into the filter (9); the position and the pitch angle of Phix3 and Phiy4 are also input into the filter after passing through the analog-to-digital transformations of A/D 7 and A/D 8; the position and the pitch angle of Phix3 and Phiy4 are filtered in the filter (9) and transformed into narrow pulses; the narrow pulses are input into a narrow wave gate pulse generator (10); the narrow wave gate pulse generator (10) generates a narrow wave gate with adjustable time and adjustable pulse width; the narrow w
