### integrated side lobe ratio

ISLR

ratio between the side lobe power and the main lobe power of the impulse response of point targets in the radar imaging scene

Note 1 to entry: The integrated side lobe ratio (ISLR) can be obtained by integrating the power of the impulse response over suitable regions. The ISLRis expressed as ISLR = 10log_(10) {(P_(text(total))-P_(text(main)))/(P_(text(main)))} where P_(text(total)) is the total power, P_(text(main)) is the main lobe power.

Note 2 to entry: The main lobe width can be taken as α times the impulse response width (IRW), centred around the peak, where α is a predefined constant, usually between 2 and 2,5.
