The problem of controlling the engagement time of an interceptor against a stationary target is considered and a two stage proportional navigation (PN) guidance law is proposed as the solution. The paper first derives the closed form expressions for PN engagement times with navigation constants of N = 1 and N = 2, respectively. Combining N = 1 and N = 2 phases, a guidance method is presented which provides a range based switching logic for achieving the desired impact time. The closed-form expression for the switching range is further analyzed for deducing maximum and minimum impact times. The proposed guidance methodology is applied to a salvo attack of multiple missiles. Extensive simulations are carried out to validate the theoretical findings.
