| 1 | The pulse envelope we obtained is a hyperbolic secant function of time. | |
| 2 | Analytical Propagation Expressions of Hyperbolic Secant Pulsed Beams with Narrowband and Broadband. | |
| 3 | When the initial power equals the critical power, the hyperbolic secant shaped spatial soliton can be obtained approximately. | |
| 4 | Being adding the offset, the tracking system will effect on the performance of trail radar in high elevation arc segment. | |
| 5 | The RMS pulse width should be used when the subcyle hyperbolic secant pulses is described. |
