Stripmap SAR: The Most Prevalent Operational Mode in Synthetic Aperture Radar Applications
Stripmap SAR represents the most widely used operational mode in SAR applications, where the radar moves at constant velocity along a straight path with a fixed squint angle between the antenna beam center and velocity direction. This discussion focuses specifically on zero squint angle conditions, known as side-looking Stripmap SAR, with additional technical insights into implementation approaches and key algorithmic considerations.
Synthetic Beam
Fundamental Radar Parameters: range resolution (thrt0) = π/6 radians, squint angle (angb) = 0.6 * wavelength / azimuth resolution, synthetic beam width. System Configuration: vertical distance from target center to flight path (Rr) = 5000 m, aircraft velocity (V) = 100 m/s. Pulse Specifications: pulse width (Tp) = 1 μs, pulse repetition interval (T) = 10 ms. Signal Processing Parameters: pulse bandwidth (B) = 0.5 * speed_of_light / range_resolution, frequency modulation rate (Kr) = B/Tp.
