In this paper the modeling of the street canyon effect in urban wave propagation is investigated. Multiple diffracted signal paths can be calculated using a simple ray tracer. However, significant power is also transmitted by a combination of wall reflection and wedge diffraction. This paper introduces a new deterministic algorithm which is able to calculate such paths using imaging techniques. Emphasis is put on the efforts made to reduce the problem's complexity since a straight forward application would suffer from enormous computing time and memory requirements. Comparisons with DCS1800 measurements show notable improvements of the field strength prediction
