EFFECT OF RADAR SYSTEM INCOHERENCE ON ACHIEVABLE MAINLOBE WIDTHS AND SIDELOBE LEVELS
Abstract
The loss in radar resolution, that is, the increase in mainlobe width and sidelobe level, has been computed for signals corrupted by a stationary random phase process. By making approximations appropriate to a coherent radar, an easily interpreted analysis is possible. The application to a CW radar or a pulsed radar using a reference oscillator with broadband phase errors is straightforward and indicates that a hash sidelobe level is introduced. A more general application, which corresponds to a crystal oscillator reference with narrowband phase errors requires the calculation of a convolution. Hash sidelobes are introduced in this case also, except that their level is a simple function of the ratio of the phase error and signal bandwidth.
